	manageTransientObjectContainer.dtml 
Log Message:
Merge chrism-pre273-branch to Zope-2_7-branch.  This checkin plus others
made to the ZODB 3.2 branch as included with the Zope 2.7 branch fix all
known sessioning issues to date.

Changes:

- TransientObject conflict resolver could potentially fail; when it
  failed, the conflict resolution machinery could resolve the
  TransientObject to None.  (never reported)

- Add a knob (not exposed to UI) to turn off "inband" housekeeping
  Housekeeping can now optionally be done using an external scheduling 
  facility by calling the "housekeep" method regularly.

- Break out actual work that _gc and _finalize do into separate _do methods
  for legibility.

- Dont raise Retry in _replentish if we're in a bucket shortage and we can't
  get the lock. Instead just soldier on and let the conflict happen naturally.

- Create a "roll" function and attempt to prevent conflicts in _gc by using a
  roll.

- Remove "nudge" function in favor of "housekeep".

- Indicators for gc required and replentish required are simpler.

- Replace BTrees.Length.Length with dunny's Length (not _p_independent) in
  order to get "number of objects in data container" right.
