My guess is that the problem was that I unpulled a buggy version of the XML
patch and replaced it with a fixed one (which I shouldn't have done).  You
probably pulled the buggy version, and then when you pulled the fixed
version they had massive conflicts which took a long time to resolve.  :(
I need to look at the conflict resolution code carefully some time to see
if I can figure out a faster way to do it.

I have an alternative fix for this, assuming you are using ghc6.  The
latest darcs uses System.Posix.Signals for the signals stuff, which should
mean that they can be moved out of win32/Posix.hs entirely, if we're
willing to drop win32 ghc5 support.

Let me know if you (both Gour and Peter) think this fix is enough, and if
so I'll pull the signal stuff from win32/Posix (or one of you could submit
a patch that does so).
