 >>> anydbm._defaultmod
<module 'dbm' from 
'/Users/drifty/cvs_code/lib/python2.3/lib-dynload/dbm.so'>

No success for me when it is using dumbdbm:

======================================================================
ERROR: test_anydbm_create (__main__.Bsddb185Tests)
----------------------------------------------------------------------
Traceback (most recent call last):
   File "Lib/test/test_bsddb185.py", line 39, in test_anydbm_create
     os.rmdir(tmpdir)
OSError: [Errno 66] Directory not empty: '/tmp/tmpkiVKcZ'

----------------------------------------------------------------------

Looks like foo.dat and foo.dir are left (files used by the DB?).  I will 
fix the test again to be more agressive about deleting files.

... done.  Just used shutil.rmtree instead of the nested 'try' 
statements that called os.unlink and os.rmdir .  Now the tests pass for 
dumbdbm.  So it seems to be dbm.so for some reason.

I will see what I can figure out or at least get as much info as I can 
that I think can help in debugging this.
