Hi, there are no restrictions as to form which thread you ev_async_send,
which means you can do that from within the same event loop.
If you don't know whether it is the same thread or not, just use
ev_async_send. If you do know that it is within the same thread that owns
the event loop, it is more efficient to start an idle watcher.
