  Log:
  Fix /dev/devctl's implementation of poll.  We should only be setting
  the poll bits when there's actually something in the queue.
  Otherwise, select always returned '2' when there were no items to be
  read, and '3' when there were.  This would preclude being able to read
  in a threaded (libc_r) program, as well as checking to see if there
  were pending events or not.
