Sounds like just the right level of noise to me.

Attached is a list of hashed repositories on code.haskell.org (including
darcs 2 repos)

Would a giant tarball of all the repositories on code.haskell.org be a
good thing here?  I have a 400M tarball in my cho home directory
(~kowey/obliterated-20.tgz) which contains repos that we did the timing
tests on way back when c.h.o upgraded to darcs 2.  It's each repo minus
20 patches, though and I don't think I can find the original.

I've got this installed on my machine and am having trouble finding any
broken CRCs.  I've also tried fetching the Agda and yi repos to no
avail.  I can confirm that this fixes my corrupt maybench repo, though.
Also, after trying darcs gzcrcs --check out of curiosity, I found my
global cache to be clean.

One thing to note is that some users have very large global caches, so
darcs gzcrcs on any one repo could be very slow.  I wonder if recycling
the --no-cache option would be useful for real users, or if it's only
relevant to folks like me who are purposefully trying to test this out.
Would it be useful maybe to advise moving the global cache out of the
way until the user is ready to cope with it and after it's been
checked/repaired once.

Thanks!
