I've seen some NFS file locking problems with the vpasswd.cdb files.
We put in alot of time trying to track it down, and I think we fixed
it. But I'm not sure since we couldn't track down exactly what was
happening. It was hard to reproduce since it was some kind of timing
issue. MySQL removes the need to lock the vpasswd files.
The only other files that need locking are the open-smtp file if you
have roaming-users enabled.
