Upgrading tdb in Samba3 to include the transaction code would fix
this, at last for databases where we can afford the slowdown that the
fsync() calls cause.

You can kill -9 a process within a tdb transaction at any time, and
you will either end up with the before or after transaction state, but
never in between.
