		1058	If L<AnyEvent::Log> is not loaded then this function makes a simple test

1150	Here be danger!
1151
1152	As Pauli would put it, "Not only is it not right, it's not even wrong!" -
1153	there are so many things wrong with AnyEvent::Handle::UDP, most notably
1154	its use of a stream-based API with a protocol that isn't streamable, that
1155	the only way to improve it is to delete it.
1156
1157	It features data corruption (but typically only under load) and general
1158	confusion. On top, the author is not only clueless about UDP but also
1159	fact-resistant - some gems of his understanding: "connect doesn't work
1160	with UDP", "UDP packets are not IP packets", "UDP only has datagrams, not
1161	packets", "I don't need to implement proper error checking as UDP doesn't
1162	support error checking" and so on - he doesn't even understand what's
1163	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	C<PERL_ANYEVENT_SUBMODULE> if they have registered the AnyEvent::Submodule
		2011	namespace on CPAN, for any submodule. For example, L<AnyEvent::HTTP> could
		2012	be expected to use C<PERL_ANYEVENT_HTTP_PROXY> (it should not access env
		2013	variables starting with C<AE_>, see below).
		2014
		2015	All variables can also be set via the C<AE_> prefix, that is, instead
		2016	of setting C<PERL_ANYEVENT_VERBOSE> you can also set C<AE_VERBOSE>. In
		2017	case there is a clash btween anyevent and another program that uses
		2018	C<AE_something> you can set the corresponding C<PERL_ANYEVENT_something>
		2019	variable to the empty string, as those variables take precedence.
		2020
		2021	When AnyEvent is first loaded, it copies all C<AE_xxx> env variables
		2022	to their C<PERL_ANYEVENT_xxx> counterpart unless that variable already
		2023	exists. If taint mode is on, then AnyEvent will remove I<all> environment
		2024	variables starting with C<PERL_ANYEVENT_> from C<%ENV> (or replace them
		2025	with C<undef> or the empty string, if the corresaponding C<AE_> variable
		2026	is set).
		2027
		2028	The exact algorithm is currently:
		2029
		2030	1. if taint mode enabled, delete all PERL_ANYEVENT_xyz variables from %ENV
		2031	2. copy over AE_xyz to PERL_ANYEVENT_xyz unless the latter alraedy exists
		2032	3. if taint mode enabled, set all PERL_ANYEVENT_xyz variables to undef.
		2033
		2034	This ensures that child processes will not see the C<AE_> variables.
		2035
		2036	The following environment variables are currently known to AnyEvent:
1896		2037
1897	=over 4	2038	=over 4
1898		2039
1899	=item C<PERL_ANYEVENT_VERBOSE>	2040	=item C<PERL_ANYEVENT_VERBOSE>
1900		2041
1901	By default, AnyEvent will be completely silent except in fatal	2042	By default, AnyEvent will only log messages with loglevel C<3>

		2044	environment variable to a numerical loglevel to make AnyEvent more (or

		2047	If you want to do more than just set the global logging level

		2072
		2073	For the rather extensive details, see L<AnyEvent::Log>.
		2074
		2075	This variable is evaluated when AnyEvent (or L<AnyEvent::Log>) is loaded,
		2076	so will take effect even before AnyEvent has initialised itself.
		2077
		2078	Note that specifying this environment variable causes the L<AnyEvent::Log>
		2079	module to be loaded, while C<PERL_ANYEVENT_VERBOSE> does not, so only
		2080	using the latter saves a few hundred kB of memory until the first message
