[Zodb-checkins] SVN: ZODB/branches/3.4/ checkCrossDBInvalidations: make this willing to wait longer in all,

[Tim Peters]

Log message for revision 30658:
  checkCrossDBInvalidations:  make this willing to wait longer in all,
  and increase the sleep time per failing loop iteration.  The hope is
  this will allow the test to pass on slower and/or "too busy" machines.
  I can't test that, though, since I couldn't get the test to fail at
  all on a Windows or a Linux box.
