Change envs_lock_ to a ReaderWriterMutex We were getting a lot of contention on this mutex because it needs to be held to run through the list of all active environments. Since this list is only rarely modified we change the lock to a ReaderWriterMutex and only lock it exclusive when we need to modify it. Test: Examine systrace of startup with DDMS monitor running.
