		1014	=item AnyEvent::postpone { BLOCK }
		1015
		1016	Arranges for the block to be executed as soon as possible, but not before
		1017	the call itself returns. In practise, the block will be executed just
		1018	before the event loop polls for new events, or shortly afterwards.
		1019
		1020	This function never returns anything (to make the C<return postpone { ...
		1021	}> idiom more useful.
		1022
		1023	To understand the usefulness of this function, consider a function that
		1024	asynchronously does something for you and returns some transaction
		1025	object or guard to let you cancel the operation. For example,
		1026	C<AnyEvent::Socket::tcp_connect>:
		1027
		1028	# start a conenction attempt unless one is active
		1029	$self->{connect_guard} \|\|= AnyEvent::Socket::tcp_connect "www.example.net", 80, sub {
		1030	delete $self->{connect_guard};
		1031	...
		1032	};
		1033
		1034	Imagine that this function could instantly call the callback, for
		1035	example, because it detects an obvious error such as a negative port
		1036	number. Invoking the callback before the function returns causes problems
		1037	however: the callback will be called and will try to delete the guard
		1038	object. But since the function hasn't returned yet, there is nothing to
		1039	delete. When the function eventually returns it will assign the guard
		1040	object to C<< $self->{connect_guard} >>, where it will likely never be
		1041	deleted, so the program thinks it is still trying to connect.
		1042
		1043	This is where C<AnyEvent::postpone> should be used. Instead of calling the
		1044	callback directly on error:
		1045
		1046	$cb->(undef), return # signal error to callback, BAD!
		1047	if $some_error_condition;
		1048
		1049	It should use C<postpone>:
		1050
		1051	AnyEvent::postpone { $cb->(undef) }, return # signal error to callback, later
		1052	if $some_error_condition;
		1053
		1054	=item AnyEvent::log $level, $msg[, @args]
		1055
		1056	Log the given C<$msg> at the given C<$level>.
		1057
		1058	If L<AnyEvent::Log> is not loaded then this function makes a simple test
		1059	to see whether the message will be logged. If the test succeeds it will
		1060	load AnyEvent::Log and call C<AnyEvent::Log::log> - consequently, look at
		1061	the L<AnyEvent::Log> documentation for details.
		1062
		1063	If the test fails it will simply return. Right now this happens when a
		1064	numerical loglevel is used and it is larger than the level specified via
		1065	C<$ENV{PERL_ANYEVENT_VERBOSE}>.
		1066
		1067	If you want to sprinkle loads of logging calls around your code, consider
		1068	creating a logger callback with the C<AnyEvent::Log::logger> function,
		1069	which can reduce typing, codesize and can reduce the logging overhead
		1070	enourmously.

1110	Here be danger!
1111
1112	As Pauli would put it, "Not only is it not right, it's not even wrong!" -
1113	there are so many things wrong with AnyEvent::Handle::UDP, most notably
1114	its use of a stream-based API with a protocol that isn't streamable, that
1115	the only way to improve it is to delete it.
1116
1117	It features data corruption (but typically only under load) and general
1118	confusion. On top, the author is not only clueless about UDP but also
1119	fact-resistant - some gems of his understanding: "connect doesn't work
1120	with UDP", "UDP packets are not IP packets", "UDP only has datagrams, not
1121	packets", "I don't need to implement proper error checking as UDP doesn't
1122	support error checking" and so on - he doesn't even understand what's
1123	wrong with his module when it is explained to him.

		1181
		1182	AnyEvent is good for non-blocking stuff, but it can't detect file or
		1183	path changes (e.g. "watch this directory for new files", "watch this
		1184	file for changes"). The L<AnyEvent::Filesys::Notify> module promises to
		1185	do just that in a portbale fashion, supporting inotify on GNU/Linux and
		1186	some weird, without doubt broken, stuff on OS X to monitor files. It can
		1187	fall back to blocking scans at regular intervals transparently on other
		1188	platforms, so it's about as portable as it gets.

		2010	them also cause AnyEvent to load additional modules - for example,

		2012	loaded.
1833		2013

1836	enabled.	2016	namespace. Other modules are encouraged (but by no means required) to use
		2017	C<PERL_ANYEVENT_SUBMODULE> if they have registered the AnyEvent::Submodule
		2018	namespace on CPAN, for any submodule. For example, L<AnyEvent::HTTP> could
		2019	be expected to use C<PERL_ANYEVENT_HTTP_PROXY> (it should not access env
		2020	variables starting with C<AE_>, see below).
		2021
		2022	All variables can also be set via the C<AE_> prefix, that is, instead
		2023	of setting C<PERL_ANYEVENT_VERBOSE> you can also set C<AE_VERBOSE>. In
		2024	case there is a clash btween anyevent and another program that uses
		2025	C<AE_something> you can set the corresponding C<PERL_ANYEVENT_something>
		2026	variable to the empty string, as those variables take precedence.
		2027
		2028	When AnyEvent is first loaded, it copies all C<AE_xxx> env variables
		2029	to their C<PERL_ANYEVENT_xxx> counterpart unless that variable already
		2030	exists. If taint mode is on, then AnyEvent will remove I<all> environment
		2031	variables starting with C<PERL_ANYEVENT_> from C<%ENV> (or replace them
		2032	with C<undef> or the empty string, if the corresaponding C<AE_> variable
		2033	is set).
		2034
		2035	The exact algorithm is currently:
		2036
		2037	1. if taint mode enabled, delete all PERL_ANYEVENT_xyz variables from %ENV
		2038	2. copy over AE_xyz to PERL_ANYEVENT_xyz unless the latter alraedy exists
		2039	3. if taint mode enabled, set all PERL_ANYEVENT_xyz variables to undef.
		2040
		2041	This ensures that child processes will not see the C<AE_> variables.
		2042
		2043	The following environment variables are currently known to AnyEvent:
1837		2044
1838	=over 4	2045	=over 4
1839		2046
1840	=item C<PERL_ANYEVENT_VERBOSE>	2047	=item C<PERL_ANYEVENT_VERBOSE>
1841		2048
1842	By default, AnyEvent will be completely silent except in fatal	2049	By default, AnyEvent will only log messages with loglevel C<3>
1843	conditions. You can set this environment variable to make AnyEvent more	2050	(C<critical>) or higher (see L<AnyEvent::Log>). You can set this
		2051	environment variable to a numerical loglevel to make AnyEvent more (or
1844	talkative.	2052	less) talkative.
1845		2053
		2054	If you want to do more than just set the global logging level
		2055	you should have a look at C<PERL_ANYEVENT_LOG>, which allows much more

		2057

		2059	the default logging settings.

		2079
		2080	For the rather extensive details, see L<AnyEvent::Log>.
		2081
		2082	This variable is evaluated when AnyEvent (or L<AnyEvent::Log>) is loaded,
		2083	so will take effect even before AnyEvent has initialised itself.
		2084
		2085	Note that specifying this environment variable causes the L<AnyEvent::Log>
		2086	module to be loaded, while C<PERL_ANYEVENT_VERBOSE> does not, so only
