The ZODB trunk is for 3.5 now.

This is news about ZEO protocol changes.  The promised
update of README.txt will have to be rewritten from
scratch for 3.4 (the new text in 3.3's README.txt isn't
quite right for the 3.4 release).

Rewrite ZEO protocol negotiation.

3.3 should have bumped the ZEO protocol number (new methods were
added for MVCC support), but didn't.  Untangling this is a mess.

Merge checkin made from a wrong project.

Believe it or not, ZopeUndo is ZEO code, not Zope code.

checkTimeoutProvokingConflicts:  try to fix rare failures.

This always slept for 3 seconds, waiting for the storage to
disconnect.  This loses on two counts:

1. Since the timeout is set to 1 second, it typically sleeps
   longer than necessary.

2. Since there's no predicting thread and process scheduling,
   3 seconds isn't always long enough, and rare failures have
   been reported against this test.

Instead we do a polling loop now.  This typically succeeds in
a little more than a second, speeding the normal case.  The
loop will continue trying for up to a minute if not.

Change default port # from 9999 to 8100, to match zope.conf
(well, on Zope trunk anyway -- the ZEO client example appears
to have gone missing from zope.conf on Zope3 trunk).
