If you have an open file descriptor, you can choose whether it is
automagically closed when you execve() something. (fcntl, close-on-exec
flag)

The basic idea is to save the internal gnutls data structure in such a
way that you only need to plug in the file descriptor and everything is
back where it was.

Why are you doing that? You're execvp-ing a new process, the data
structures will vanish anyway -- and you risk closing the sockets when you
do this.

Does that call work when you use it *before* doing your
save-execvp-restore dance?
