Summary: ZEO 1.0 commit lock problem

Initial Comment:
ERROR: checkCommitLockOnAbort
(ZEO.tests.testZEO.ZEOFileStorageTests)
----------------------------------------------------------------------
Traceback (most recent call last):

error: release unlocked lock

I've seen this error occasionally when running the unit
tests for ZEO 1.0 branch.  I can't reproduce it when
zLOG is enabled.

It presumably has something to do with the new code to
implement suspend and resume for the distributed commit
lock.
