Follow-up Comment #10:

With the attached patch, Rik's  tst_ctrlc  can successfully be interrupted
well over 90% of the time on my system.

It is certainly not a real solution to the problem, but I think the real
solution would required giving ATLAS and OpenBLAS new functionality to allow
pthread_kill.

I have no idea how this will work with other OSes or BLASes.

I'm not sure if ensure_exit and force_exit should be put in sighandlers.cc. 
That is the natural place, but I'd like the Kludge to be limited to as few
files as possible, and having them in toplev.cc also allows them to be
static.

Some of the things should probably be shielded by #if defined()s.

I'd really love feedback on this.  Thanks!
