+   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)
