Using the _seq unique ID stuff in msql, we are seeing corrupted databases
with duplicated rows, just plain garbage, and other anomalies.

It's acting as if some modification to an mmap'd page is getting lost
somewhere.

This is under a version of FreeBSD from around January.  Will upgrade and
see if it still happens.


I'm pretty suspicious of our mmap.  Is there some kind of a test suite out
on the net?
