Which mutex would that be?

I've grepped a bit through the code, and the usage pattern seems to be a
la: 

    pending_funcalls
      = Fcons (list3 (Qrun_hook_with_args,
                      Qdelete_terminal_functions, terminal),
               pending_funcalls);

I don't see any obvious mutexes...

I've also grepped around for pthread_* stuff, and in particular
pthread_create, and I can't really find anything.  Do you have an
example of a code snippet that uses a thread inside Emacs?
