/* IMPORTANT: tdb_wrap should be always prefered over tdb_context for end consumer functions
it's because if the code will be running inside smbd, then we must use the linked list
of open tdb files, to determine if the tdb we desire is already open
as otherwise, when you close the tdb (even on a different file descriptor),
ALL LOCKS are lost (due to a real screwup in the POSIX specification that nobody has been able to get fixed)
