Thanks for the detailed report.  I think we aren't going to be able to
address this for the 2.5 release, but I will put it on my list of
things to do to see if we can duplicate this issue on another machine
and start figuring out what is going on.  We'll try to put a test case
for something like this together for the 2.6 release just to confirm
that we are within the realm of possibilities for estimation.
