It would be useful to have a threaded self-test in GnuTLS too -- if you
have a minimal test case that initializes gcrypt and does some gcrypt
testing in two (or more) parallel threads, it would be great if you
could contribute that to GnuTLS too, and I can adapt it to do TLS
sessions in each thread.

I'm thinking it would be nice to a have a threaded version of
tests/mini.c which does in-process TLS negotiations.  It could set up
two threads that talked to each other with its own push/pull functions
protected by a mutex.
