We have 3 reports from Sven Joachim, Nix, and Carsten Mattner.  I will
do my best to find the issues.  They seem to be in the C code I wrote to
link with GnuTLS.

It would be really helpful if someone who knows C debugging well could
run Valgrind or something similar against Emacs with GnuTLS compiled,
hitting all these leaks.  I will take a look at the code, since I am
also reviewing it to prevent the lockups on hung connections, but
concrete Valgrind reports would be great.
