The custom network daemon I am ready to take blame for, but what is
intriguing is that httpd - from the standard httpd rpm - starts and is
left running. Perhaps I'm doing something wrong.

Hmmm. httpd might be buggy in that regard. We are also installing
mod_perl, mod_python and mod_php, any of those might be trying to
(incorrectly) reload httpd.
