Except that Postgres and Oracle are both pretty slow in comparison to
bsddb.  OracleStorage, untuned, is about 30 times slower than
FileStorage on the same hardware.  bssdbStorage on the other hand is
about 2 times slower than FileStorage.  bsddb is also easier to develop
for.

Not too much to add other than mounting is an area for improvement!
