It can, and the performance hit is negligible IMHO. Heck, debian cron can
detect and reload configuration on the fly for a file and an entire
directory of files, and it does that check every minute. Nobody ever
complained, AFAIK.

Not only that, but you also only need to check the menu tree for changes
when the user requests the menu. It will delay the menu's drawing a bit if
there were indeed changes... which is quite acceptable.
