Comment(by igloo):
I looked into a slowdown higher up in the dependency tree:
Timing compilation of the attached 4270.hs with `ghc -c 4270.hs -O`, with
6.12.2 and HEAD, with and without `USE_PRAGMAS` defined:
|| || 6.12.2 || HEAD ||
|| USE_PRAGMAS || 1.60s || 5.67s ||
|| No USE_PRAGMAS || 1.76s || 1.84s ||
My hunch is that HEAD is paying more attention to INLINE pragmas, and so
generating more code, and thus using more memory.
