Hash :4632b78e Message :Minimize calls to base_notify implementation functions, thereby avoiding needless syscalls
The trick here is that if we already told the base to wake up, and it
hasn't woken up yet, we don't need to tell it to wake up again. This
should help lots with inherently multithreaded code like IOCP.
