In future, this may happen, and we don't want to clobber them.

thread/fork safe tdb_reopen_all() should be a noop".
This version just wraps the reopen code, so we still re-grab the lock and do
the normal sanity checks.
The reason we do this at all is to avoid global fd limits, see:
http://forums.fedoraforum.org/showthread.php?t=210393
Note also that this whole reopen concept is fundamentally racy: if the parent
goes away before the child calls tdb_reopen_all, the database can be left
without an active lock and another TDB_CLEAR_IF_FIRST opener will clear it.
A fork_with_tdbs() wrapper could use a pipe to solve this, but it's hardly
elegant (what if there are other independent things which have similar needs?).

tdb_reopen_all() should be a noop"
This reverts commit e17df483fbedb81aededdef5fbb6ae1d034bc2dd.
tdb_reopen_all also restores the active lock, required for TDB_CLEAR_IF_FIRST.

should be a noop
The reason for tdb_reopen_all() is that the seek pointer on fds are shared between
parent and child.
