Ok, I have committed the patch and the default behavior is to wait up to
50 ms instead of 10 ms (which was the previous default).  For waits longer
than 1 ms, msleep is used instead of DELAY.  I'm hoping 50 ms is enough to
even get rid of your occasional timeouts.  I changed the error code to be
more descriptive than AE_ERROR so that is intentional.

Let me know if there are any problems.
