There's no hardcoded size limit as far as I know, but it depends on which DBM
implementation you are using.  Some are better than others.

The DB files are set up for random access, so all the cleaner does is poke holes
in it which are then available for re-use in future.  To physically shrink the
file, you'd have to write something in Perl which created two DBM tied hashes,
copied the contents of the live one to the backup, and untied the hashes.  Then,
backup the old file and move the new file over it.

Best Wishes,

Paul.
