| Description: | Event loop abstraction layer that libraries can use for evented I/O.
In order for async based libraries to be interoperable, they need to use
the same event loop. This component provides a common LoopInterface that
any library can target. This allows them to be used in the same loop, with
one single run call that is controlled by the user.
In addition to the interface there are some implementations provided:
* StreamSelectLoop: This is the only implementation which works out of the box
with PHP. It does a simple select system call. It's not the most
performant of loops, but still does the job quite well.
* LibEventLoop: This uses the libevent pecl extension. libevent itself supports
a number of system-specific backends (epoll, kqueue).
* LibEvLoop: This uses the libev pecl extension (github). It supports the same
backends as libevent.
* ExtEventLoop: This uses the event pecl extension. It supports the same
backends as libevent.
All of the loops support these features:
* File descriptor polling
* One-off timers
* Periodic timers
* Deferred execution of callbacks
