[development] How to make Require_once refreshable

I was trying to track down an issue I am having with the node module's content_types.inc so I stuck in some messages. Unfortunately, the menu system uses require_once to load these files, so my changes are not working. I really don't want to have to reboot every time I do something. Is there any quicker way to get PHP to reload these files? Nancy E. Wichmann, PMP Injustice anywhere is a threat to justice everywhere. -- Dr. Martin L. King, Jr.
