I would disagree here. I start rc scripts from wily all the time. They are really short
and my SS2 needs all the help it can get to make things faster.

Ofcourse, I do not use readline and run the scripts in sequence, so the memory savings would 
not be great (or?, what sizes accompany the rc.static, rc.dynamic, xxx)

Yes, I agree here. But a shell is special, (my usage of rc is special :-) it is started lots of times, finnishes
quickly and is not run many times in parallell.
