Subject: If the main event queue is not empty, call select() with zero timeout, so
X-Git-Tag: v1.2.0~1450

If the main event queue is not empty, call select() with zero timeout, so
that the events are ran again after the FD's are checked. This allows us
to schedule I/O checks between processing of user commands.
