Main function is now to provide referenced api documentation.
Use CacheInRam or CacheOnDisk instead which are derived from this class.
Attentions, Michele says:
There are signatures inside gdbm files that are used directly
by the python gdbm adapter that often are lagging behind in the
detection code in python part.
On every occasion that a gdbm store is probed by the python adapter,
the probe fails, because gdbm file version is newer.
Using gdbm directly from C would work, because there is backward
compatibility, but not from python!
The .shelve file is discarded and a new one created (with new
signature) and it works until it is probed again...
The possible consequences are memory leaks and broken sessions.
