* Call select() on the pending ports and move any ready ones to the ready
* queue. If wait is true, seconds is either -1 (wait forever) or the
* maximum number of seconds to wait (with ticks any additional ticks).
* The returned value is a status code.
if there are no ready ports, then the function moves no pending ports
to the queue. So the initial test
if ((! wait)
&& (pending.first == NULL))
is too narrow. We should exit with NO_ERRORS whenever there are no
pending ports, no matter the value 'wait'. This is the same effective
behavior as a select() call that finds no ready ports. The
replacement code should be
if (pending.first == NULL)
I'm running a custom build with that patch to look for any weird
impact, and it has been looking good so far.
