nxsig_abnormal_termination() popped the thread's pthread cleanup
handlers in the kernel, so in the protected and kernel builds a process
could get its own code called with kernel privilege by raising a fatal
signal. POSIX runs cleanup handlers on pthread_exit() and on acting upon
a cancellation; termination by a signal is as if by _exit(), which runs
none.
