I did make a change subsequent to your turning off this code. Maybe
that was enough to get things working. Either that or, if you are using
the trunk code, maybe you aren't hitting this at all anymore since there
are overlapped I/O accomodations.
Anyway, I wouldn't mind giving the code another try if you are up for
it. Although I didn't write the code originally, it has always bothered
me that it didn't work because it seems like it should have.
Shall I turn it on, create a snapshot, and then ask our legion of
testers to try it?
