Interpreter change

[John M McIntosh]

The other thing I'm confused about is that in the past
ioRelinquishProcessorForMicroseconds()

where we would calculate the pending wakeup time based on my thoughts  
of a few years ago then we would
have said aioPoll(realTimeToWait)....

and the aioPoll() logic would do it's thing for the supposed set of  
micro seconds.

However now I see that this has changed to:

	if (!aioPoll(0)) {
		  struct timespec rqtp= { 0, realTimeToWait * 1000*1000 };
		  struct timespec rmtp;
		  while ((nanosleep(&rqtp, &rmtp) < 0) && (errno == EINTR))
			rqtp= rmtp;
	}

so why the change not to have the select() do the sleep?

what are the conditions that would cause aioPoll() to return 0, thus  
invoking this nanosleep
and if the nanosleep is invoked, would 16 ms pass before servicing a  
socket? if realTimeToWait is 16ms?
