$ httpd -d/some/path

Excerpt from /some/path/httpd.conf:

ServerRoot /some/other/path

This is perfectly legal. But the server has already made configuration
decisions based on "/some/path". So Apache starts up, reads config files,
then shuts down, and forgets everything except the configuration details,
and does it all again. This had been determined to be the "best" way of
doing things.

And as has been mentioned already, a module should be able to handle
restarts, as many of them in close proximity as the server can (and Apache
can handle quite a lot in a short amount of time). So having Apache start
and stop and start again at startup ensures that module authors don't
screw this up.
