9.2.0 did have an occasional problem with timeouts because of a problem
with the select loop but should only have been seen when there was no
activity on the machine. 9.2.1 fixed that but at the expense of making the
select timeout too short and having it become compute bound. 9.2.2rc1
should be just right. 9.3.0 will totally eliminate these problems as it's a
rewrite of that piece of code. Unfortunately it's not yet available even in a
snapshot.

You need to let us know.
