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?
