Can you elaborate on this?
To be clear, the locking on the sh script is unsafe. It was written
before we understood the need for global locking of the sam.ldb, so
needs to be replaced.
Unsafe locking, particularly of the type seen here (because the per-db
and per-record locks are still respected) is dangerous because it
appears to work most of the time, but can be subtly corrupt.
