+/* 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)
