Back to the old problem... Eric Cholet has implemented
$Apache::Server::Restarting, but for various reasons it's never went in.
Currently I think there is a slight "bug" in the latest mod_perl 1.x,
where PerlRequire doesn't work as require() in Perl per se on restart. A
few people have reported this behavior.
So as a quick workaround do this:
start.pl:
---------
require "real-startup.pl";
this require(), won't be called twice.

I'm not underestimating the power of your patch of course :) I think the
real fix should be in PerlRequire.
BTW, the same problem happens to PerlModule. I've moved all my preloadings
into the Perl domain, mod_perl reloads them twice.
