Hmmm.  I may have been wrong; it's just my impression that
mod_proxy_fcgi had essentially been abandoned.

dev@httpd and/or bugzilla.  But that depends on someone who's
actually worked on it being motivated to respond, and mod_fcgid
reduces the likelihood of that happening.

Now that makes sense - and indeed ties into something I'm trying to
work towards (but don't expect anything exciting anytime soon).
Posting something based on that to dev@ might be more productive than
a long/rambling report that you have to read in detail before confirming
it looks like a bug (as opposed to a user error).

If mod_fastcgi has capabilities that are missing in mod_fcgid and
that you have a use for, that may be worth turning into a feature
