Well, deprecated in the sense that we are beginning to realize there is
probably a serious problem with dumbdbm.  I think we may have to make the
code reject dumbdbm for new databases and support it for existing databases
only if the application is started with a command line flag to force it.  I
strongly suggest you get ahold of bsddb3 (aka PyBSDDB) and install it, then
ditch dumbdbm.
