unix: fix event loop block, prepare/check invoke

Browse Source 
Don't block in epoll_wait() / kevent() / etc. syscall unless there are active
handles. If there are only active requests, do a non-blocking poll.

Likewise, don't run the prepare and check watchers unless there are active
handles *or* requests.
