DEFUN ("process-contact", Fprocess_contact, Sprocess_contact,
       1, 2, 0,

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.
