And, my point back to you is that should be part of the documentation
of the module NOT of httpd-2.0.  Making broad statements that will
confuse our users like "threaded MPMs may not be suitable for serving
up dynamic content" is a ridiculously overbroad and inaccurate

A better statement may be: "Some PHP or Perl modules may not
interact well with a threaded MPM in httpd-2.0.  Caution is urged
when using a threaded MPM."  To me, that totally belongs in the
PHP or Perl documentation.  That is a limitation of PHP and mod_perl
not of httpd-2.0.

That statement doesn't hold for a mod_jk2 (or whatever the latest
httpd-2.0 Tomcat module is).  It totally depends on how the 3rd
party module is architected not on the architecture of the web
server itself.  -- justin
