  Log Message:
  -----------
  For epoll aio, close and reopen the epoll fd in forked child process
Factor the epoll initiation out of aioInit into new epollInit function
and invoke it via pthread_atfork in the child process after a fork.
Prevents misdelivery of events from the common kernel epoll structures.
