Review request for geode and anilkumar gingade.


Changes
-------

The previous fix caused a deadlock because of lock inversion on the queueHeadLock and the blockGCLock.
This fix introduces a new lock used when modifying or iterating the expiredTombstones.
Tests that failed with the previous deadlock are now passing.
