I think the code that triggers this deadlock was in bug 1325341 (since the lock is `mRCWNLock`), so it has been there for years. I think it's probably some recent changes that affect the thread timings and make this deadlock happen more often.
Unfortunately,  I can't tell how many users are affected, since it's all about timing to hit this.
