All C<ev_prepare> watchers are invoked just I<before> C<ev_run> starts
to gather new events, and all C<ev_check> watchers are invoked just after
C<ev_run> has gathered them, but before it invokes any callbacks for any
received events. Callbacks of both watcher types can start and stop as
many watchers as they want, and all of them will be taken into account
(for example, a C<ev_prepare> watcher might start an idle watcher to keep
C<ev_run> from blocking).
All C<ev_prepare> watchers are invoked just I<before> C<ev_run> starts to
gather new events, and all C<ev_check> watchers are queued (not invoked)
just after C<ev_run> has gathered them, but before it queues any callbacks
for any received events. That means C<ev_prepare> watchers are the last
watchers invoked before the event loop sleeps or polls for new events, and
C<ev_check> watchers will be invoked before any other watchers of the same
or lower priority within an event loop iteration.
