 hits swap. I usually kill it at that point.

 What's the output up to that point? i.e. what has it compiled, and what is
 it currently compiling?

 Here, my HEAD ghc (as compiled by validate) finished with I think around
 1G RAM used:
 {{{
 166.70s user 2.10s system 101% cpu 2:46.41 total
 }}}
 I'll do more testing, e.g. with 6.10, later.
