Ah, for running a large test suite (like the stdlib's). That makes sense.

From the initial report ("in particular linecache") it seems at least possible that there's really just one cache that's a real issue, in which case there's a pretty obvious fix. (And making it possible to use linecache in a bounded way, instead of all-or-nothing clearing, might be useful for other purposes besides this...) But I don't know if that really is the case; did anyone check whether the 500MB were 90%+ in linecache or anything like that?
