		384	=head2 EVENT SYSTEM
		385
		386	OpenCL can generate a number of (potentially) asynchronous events, for
		387	example, after compiling a program, to signal a context-related error or,
		388	perhaps most important, to signal completion of queued jobs (by setting
		389	callbacks on OpenCL::Event objects).
		390
		391	To facilitate this, this module maintains an event queue - each
		392	time an asynchronous event happens, it is queued, and perl will be
		393	interrupted. This is implemented via the L<Async::Interrupt> module. In
		394	addition, this module has L<AnyEvent> support, so it can seamlessly
		395	integrate itself into many event loops.
		396
		397	Since this module is a bit hard to understand, here are some case examples:
		398
		399	=head3 Don't use callbacks.
		400
		401	When your program never uses any callbacks, then there will never be any
		402	notifications you need to take care of, and therefore no need to worry
		403	about all this.
		404
		405	You can achieve a great deal by explicitly waiting for events, or using
		406	barriers and flush calls. In many programs, there is no need at all to
		407	tinker with asynchronous events.
		408
		409	=head3 Use AnyEvent
		410
		411	This module automatically registers a watcher that invokes all outstanding
		412	event callbacks when AnyEvent is initialised (and block asynchronous
		413	interruptions). Using this mode of operations is the safest and most
		414	recommended one.
		415
		416	To use this, simply use AnyEvent and this module normally, make sure you
		417	have an event loop running:
		418
		419	use Gtk2 -init;
		420	use AnyEvent;
		421
		422	# initialise AnyEvent, by creating a watcher, or:
		423	AnyEvent::detect;
		424
		425	my $e = $queue->marker;
		426	$e->cb (sub {
		427	warn "opencl is finished\n";
		428	})
		429
		430	main Gtk2;
		431
		432	Note that this module will not initialise AnyEvent for you. Before
		433	AnyEvent is initialised, the module will asynchronously interrupt perl
		434	instead. To avoid any surprises, it's best to explicitly initialise
		435	AnyEvent.
		436
		437	You can temporarily enable asynchronous interruptions (see next paragraph)
		438	by calling C<$OpenCL::INTERRUPT->unblock> and disable them again by
		439	calling C<$OpenCL::INTERRUPT->block>.
		440
		441	=head3 Let yourself be interrupted at any time
		442
		443	This mode is the default unless AnyEvent is loaded and initialised. In
		444	this mode, OpenCL asynchronously interrupts a running perl program. The
		445	emphasis is on both I<asynchronously> and I<running> here.
		446
		447	Asynchronously means that perl might execute your callbacks at any
		448	time. For example, in the following code (I<THAT YOU SHOULD NOT COPY>),
		449	the C<until> loop following the marker call will be interrupted by the
		450	callback:
		451
		452	my $e = $queue->marker;
		453	my $flag;
		454	$e->cb (sub { $flag = 1 });
		455	1 until $flag;
		456	# $flag is now 1
		457
		458	The reason why you shouldn't blindly copy the above code is that
		459	busy waiting is a really really bad thing, and really really bad for
		460	performance.
		461
		462	While at first this asynchronous business might look exciting, it can be
		463	really hard, because you need to be prepared for the callback code to be
		464	executed at any time, which limits the amount of things the callback code
		465	can do safely.
		466
		467	This can be mitigated somewhat by using C<<
		468	$OpenCL::INTERRUPT->scope_block >> (see the L<Async::Interrupt>
		469	documentation for details).
		470
		471	The other problem is that your program must be actively I<running> to be
		472	interrupted. When you calculate stuff, your program is running. When you
		473	hang in some C functions or other block execution (by calling C<sleep>,
		474	C<select>, running an event loop and so on), your program is waiting, not
		475	running.
		476
		477	One way around that would be to attach a read watcher to your event loop,
		478	listening for events on C<< $OpenCL::INTERRUPT->pipe_fileno >>, using a
		479	dummy callback (C<sub { }>) to temporarily execute some perl code.
		480
		481	That is then awfully close to using the built-in AnyEvent support above,
		482	though, so consider that one instead.
		483
		484	=head3 Be creative
		485
		486	OpenCL exports the L<Async::Interrupt> object it uses in the global
		487	variable C<$OpenCL::INTERRUPT>. You can configure it in any way you like.
		488
		489	So if you want to feel like a real pro, err, wait, if you feel no risk
		490	menas no fun, you can experiment by implementing your own mode of
		491	operations.
