Since when is subprocess communications "outlawed" in Emacs for
significant features that need to have good performance?  The above is
IME a mistaken conclusion; following it will preclude us from using
many useful external programs.  So please don't accept that as an
axiom.

Also, linking against a library instead of communicating with a
program has its disadvantages as well: if the library crashes, so does
Emacs.
