Now __stack_chk_fail calls abort(3) directly, we terminate with SIGSEGV rather than SIGABRT. (Because of the workaround for the debuggerd lossage in the abort(3) implementation, which was the motivation for switching __stack_chk_fail over to abort(3).) Also clarify the comment on the weird pthread death test, so it doesn't get copied and pasted onto real death tests. Change-Id: Ie832eaded61359c99e7a10db65e28f35e8f63eed
