a� A dumb and slow but simple dbm clone.
For database spam, spam.dir contains the index (a text file),
spam.bak *may* contain a backup of the index (also a text file),
while spam.dat contains the data (a binary file).
XXX TO DO:
- seems to contain a bug when updating...
- reclaim free space (currently, space once occupied by deleted or expanded
items is never reused)
- support concurrent access (currently, if two processes take turns making
updates, they can mess up the index)
- support efficient access to large databases (currently, the whole index
is read when the database is opened, and some updates rewrite the whole index)
- support opening for read-only (flag = 'm')

The flag argument, used to control how the database is opened in the
other DBM implementations, is ignored in the dbm.dumb module; the
database is always opened for update, and will be created if it does
not exist.
The optional mode argument is the UNIX mode of the file, used only when
the database has to be created. It defaults to octal code 0o666 (and
will be modified by the prevailing umask).
