I introduced a deadlock avoidance into 1.4, which I attempted to port to trunk as well.

Unfortunately, since trunk uses read/write locks for the context lock, it means that I have
actually *introduced* a deadlock condition since they are not recursive. Removing this change
for now and will look into introducing a different one.
