I wouldn't do this here for two reasons. 1. Putting raw Forth into a *.rc file isn't recommended (only words that take their arguments from the text input buffer [TIB] -- aka "source" in FreeBSD ANS Forth under loader(8) -- should appear in *.rc), and 2. The loader.rc file shouldn't really be touched if you can help it (we should think about instead moving the logic to the "start" function which is already above -- that means that loader.rc stays minimal and architecture dependent, whereas the feature we're talking about adding is not architecture dependent).
