Following on from the FtD review discussion documented here:
http://cwiki.apache.org/confluence/display/qpid/FtD+Code+Review+Notes
The changes to priority queue are not thread safe so cannot guarrantee messages
will be correctly kept in memory.
This task includes:
19 0.5 H _priorityListsindex.memoryUsed() + requriedSize is not
threadSafe. Currently hard to reason about.
21 0.5 H PriorityQueueEntryList add() not thread safe. Reclaiming memory
and then setting later is not atomic.
24 0.5 H setMemoryUsageMaximum / setMemoryUsageMinimum : not ThreadSafe
- synchronize
17 0.5 H Document atomicity of memory counting
