DEFUN ("process-contact", Fprocess_contact, Sprocess_contact,

If PROCESS is a non-blocking network process that hasn't been fully
set up yet, this function will block until socket setup has completed. */)

if (NETCONN_P (process))
wait_for_socket_fds (process, "process-contact");
So this function is advertised as blocking if called on an incompletely
set-up connection, which seems to be the case here. And it's never
going to be completed, which can happen...
I'm not sure what the right fix here would be.
