[PATCH] D29588: Use rw locks for sanitizer thread registry

> Sharing a mutex access across threads like this is not supported by blocking mutex

Why?
I've checked BlockingMutex comments and linux/mac/win implementation. I don't see any indication that it's not supported.
How is RWMutex different?
How does the problem manifest? What is the scenario that demonstrated the problem?
