LGTM. The init/deinit code should not be performance critical, so i think having a mutex is ok. Now that RefCount is not atomic, there should not be any confusion about any future usage, it would have to be protected by the mutex.

In addition, I did some testing with OMPT and this patch since OMPT has some ordering constraints. That appeared ok too.
