I believe that IP does not support pyd modules (that is DLLs for Python)
which is where the real support for dbm on Windows comes from.  As such
the shelve module can't currently be supported well (dumbdbm is not very
good. :))

Additionaly some mode flags to open() don't work quite right in IP1.0,
but I *think* they are fixed in the latest 1.1 (not sure...)
