- It is no longer necessary to symbolically link cPickle or
        ZServer. ZServer is no longer necessary at all.

        ZServer. ZServer is no longer necessary at all.

      - A Zope-style INSTANCE_HOME and var directory are no longer
        needed.

      - If ZServer *is* available, the medusa monitor server can be
        used in the storage server.

      - An option, -d, was added to facilitate generation of a
        detailed debug log while running in the background.

The question is, do we even need Overridable any more?

on some platforms. Added Python wrapper modules to preserve official
names.

which will help new storage writers.

Creating the reference list when one isn't passed is a bonus.

they are used. This is important to keep used data structures in
memory when the ZODB garbage collector is busy.

Added Id strings.

in Catalog when a sort-index is used. Waaaa.

should seal the concurrency bug: the map was being set to None, resulting
in potentially two threads servicing the same queue and making it impossible
to reliably create a ClientStorage once the main loop is running.

Optimized pickle formats (using tuple rather than tuple of tuples).

Updates Interfaces file with set operations and byValue method.

(re)Implemented new set operations and added byValue method.

Fixed bug in handling of empty BTreeItems.

Rewrote suite building to use a test_suite function as required by
Brian's test runner.

Added a debug function and a new __main__ handler that can run it.

Added flags to prevent subclasses from having instance dictionaries.
It's not clear that people will actually subclass these things and
supporting instance dictionaries adds extra effort at this time, which
we can't afford.
