Exclusive locking when a process tries to write.  At that time,
no other process should be able to access the database.

I don't know what happens when two processes try to access the
same database at the same time.  If the locking is programmed
properly ( I didn't check this ) then at least you can be sure
no data corruption will occur.  Perhaps a read will fail when
another process writes, dunno.
