For get_delete_on_close_flag() we don't need to go through
the whole get_share_mode_lock() thing, a special routine
just doing the tdb_read without an app-level lock is
sufficient. And this I think should not hurt too badly.

tdb still does the lower-level locking, and it also does the
malloc. One of tridge's plans always was to have a
tdb_fetch_locked_ro() (or something similar) that does not
do the malloc and provides direct access to the mmap region.

This should be sufficiently fast then I think.

I know, this can become addictive. :-)
