We do it like this in the CMUCL backend. It means that a
single-threaded Lisp will be blocked while it's in a dialogue with
Emacs. I think it's the Right Way.

It seems like the main alternative is to implicitly call the
SERVE-EVENT loop on EWOULDBLOCK. As an Erlang programmer this strikes
me as a Really Bad Idea, but it might be practical for others :-)
