gnutls functions were never designed as pthread cancellation points. I
have not thought that much, but I believe your main concern is memory
leaks right? It may be that if you deallocate the session in another
thread it may just work; though you may have to create a stress test
for that to verify that this is possible.

I assume that you are describing threads (you can always terminate a
process). The answer is as above.
