i should be more clear on this, the magic numbers don't work. this exposes the fact that this code is making assumptions that aren't called out. it's best to avoid those by letting the kernel place the segment. the kernel indeed has the information to place this segment correctly. ... or should have---there's a bug in the labs kernel where an automaticly placed segment can collide with the temporary stack. i solved this by putting the temporary stack above the normal stack, but i think there was some thought that there were better ideas. i felt that running a placement algorithm on the temporary stack for every exec was excessive. - erik
