We should really use a C implementation of SHA1, the Haskell version isn't buying us anything beyond being a stress test of the register allocator.
.. and perhaps a test case for too much code unfolding in GHC? Sounds like bugs to me. :) If you turn down GHC flags the pressure also goes away. Ian: Did this problem result in Intel CC / GCC register allocator freakouts? Ben.
