Log Message:
t_arc4random: Test arc4random_global.per_thread, not .initialized.
If arc4random_initialize has been called, and thr_keycreate failed,
then .initialized will be true but .per_thread will be false -- and
.thread_key will be garbage (some other thread key for another
purpose, most likely). This path was enabled by allowing
thr_keycreate to fail instead of aborting the process.
This hasn't caused trouble yet, mainly because we don't do anything
to inject faults into thr_keycreate in these tests. Tweak the
global_threadkeylimit test while here to provoke a crash with the
wrong conditional.
Fix a similar edge case in the little test program embedded in
arc4random.c (which should maybe just go away now that we have atf
tests).
