By re-locating the file, we do not need to change the contents of the file,
and can still fix the import problem.

Add test for upward traversal

if one tries to embed Zope within C/C++.

Made a small fix to _setDB in Mount.py to pass 
through new args passed to it.

With these changes, Zope now runs again.

- Reformat code, add docstrings, unobfuscate local var names
- Eliminate use of hasattr and simplify where possible
- Add comments
- Improve test coverage

  until a bucket is garbage collected (which may be much later than the
  expiration of that bucket), we "finalize" a bucket as soon as possible
  after it gets expired.  This effectively means that the "delete notifier"
  will be called much closer to the time that a transient object actually
  expires.
                                                                                
- Add a "_last_finalized_timeslice" counter; this counter keeps track of 
  the bucket which was finalized last.  Set the initial value of
  "_last_finalized_timeslice" to -period; this services the unit tests for
  finalization, where there can actually be a timeslice that is 0 and we 
   need to finalize that bucket.
                                                                                
- Add a series of locks to prevent finalization, replentishment, and
  garbage collection from being attempted by more than one thread
  simultaneously.
                                                                                
- Add "Fake" module for interactive testing purposes (swap out BTree for
  simpler object during stress tests for isolation purposes).
                                                                                
- Allow DATA_CLASS to be specified (this is the main data structure
  class).

- Update docs and tests to account for new finalization strategy.
