Cloned from: 354009: DeadLock in CDO Session
https://bugs.eclipse.org/bugs/show_bug.cgi?id=354009

Build Identifier: I20110613-1736

+ While performing our tests we encountered a DeadLock in CDO that seem related to CDOSession/View invalidation.
+ This could not be reproduced in a unit test, a snapshot has been provided to Eike to inspect the threads behaviour
+ When running using yourkit profiler, dead lock was detected, here's the relevant thread information from the snapshot :
