Sorry for confusing my 2 separate requests:

1. How to detect that a process filter is running, in Emacs 21, so that
   I can help someone still using my legacy code.  I should have posted
   that question to gnu.emacs.help.

2. If that's not possible, how Emacs 22 might provide such a feature,
   for its general utility to Emacs Lisp programmers.  It sounds like
   the this-process variable may be implemented -- perfect!

Thanks,
