--- Comment #11 from Konstantin Belousov <kib at FreeBSD.org> ---
(In reply to Ngie Cooper from comment #10)
There is no underlying issue.  Behavior of pthread_cancel() is undefined if the
argument does not reference valid running thread.

Also, in SUSv7TC2 I only see the statement that pthread_cancel() shall not
return EINTR, there is no single word about EINVAL being forbidden.
