Exactly. iPIII-800/192M ram died on me swapping when I tried to run
compiled version with 16M big stack and input file with 100000 children in
one node.

I tried this with ghc 5.02, and it run in 20M RAM or so. It could be less,
but at least it runs, and not segfaults as hugs :)

Is it's distribution restricted? Is it possible to get it somwhere, use it,
patch it, etc?
