Correct detection of a thread termination
Summary:
Stop using the Linux solution with pthread_key_create(3).
This approach does not work on NetBSD, because calling
the thread destructor is not the latest operation on a POSIX
thread entity. NetBSD's libpthread still calls at least
pthread_mutex_lock and pthread_mutex_unlock.
Detect _lwp_exit(2) call as it is really the latest operation
called from a detaching POSIX thread.
This resolves one set of crashes observed in
the Thread Sanitizer execution.
