I built a darcs-unstable from today's sources (18 Feb 2008), and it hangs
eating all my memory whan I try to 'darcs check' a GHC repository (darcs2
format).
The reason I'm trying this is because I have a darcs2 from a couple of
weeks ago built with bytestring support, that fails to 'darcs check' the
GHC repository, claiming an inconsistency. I'll report this separately, as
the issue may still exist.
