 Log Message:
 arc4random(3): Avoid failure due to thread key limits.
 
 If thr_keycreate (a.k.a. pthread_key_create) fails, fall back to
 using globally serialized state instead of per-thread state.  This is
 unlikely to happen but arc4random(3) should work even if it does.
 New test case forces exercising this path (at least, simulating the
 effect of key creation failure).
