If you create a script to add & delete the same 50,000 users, and then re-run
that script multiple times, the MDB database on disk continues to grow, despite
the fact that we are only adding and deleting the same data repeatedly.  There
should be zero growth to the database.

Instead, the data.mdb file went from 108MB in size to over 1.2GB after 5-6 runs.
 Time to add/delete all the users went from 3 minutes 32 seconds on the first
run to over 90 minutes on the final run (5th or 6th, I lost count).
