Emulation has a price - hopefully things will speed up with the
release of beta19, although the ghc compilation speeds I'm seeing on a
PPro/64M system aren't that much worse than on a sanely equipped Ultra
Sparc.
It is our intention to move away from this emulation layer as much as
possible for ghc compiled binaries though, i.e., you don't
have to distribute the cygwin.dll with your apps. A secondary benefit
of this will hopefully be some speedup.
