I believe you should be able to import any module you want in your
handler module, even if the handler doesn't use the module directly, and
have reload() work as expected.  This way you can keep any special debug
flag action in the handler module and the other modules never need to

Another option is starting httpd with -X, in which it runs in single
process mode and I think dumps log info to the standard out.  If your
going MaxChild 1, might as well go the full monty with httpd -X =p
