Shawn Wilsher 11b33f0ab8 Bug 506805 - Remove locking in AsyncExecuteStatements
This removes the use of the shared mutex in AsyncExecuteStatements.  We now rely
on PR_AtomicSet and the volatile keyword.  This results in zero lock contention
between the calling thread and the background thread if cancel is ever called.
