=item

=item Coro::EV::loop

You have to call this function instead of EV::loop, EV::dispatch and
similar functions. EV is not generic enough to let Coro hook into yet, so
you have to use those replacement functions.

=item $revents = Coro::EV::timed_io_once $fd, $events, $timeout

Blocks the coroutine until either the given event set has occured on the
fd, or the timeout has been reached (if timeout is zero, there is no
timeout). Returns the received flags.

=item Coro::EV::timer_once $after

Blocks the coroutine for at least C<$after> seconds.
