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).
