I tried to reproduce issue940, but in doing so I managed to get some
Hash failure error messages.
The key is that I was trying to concurrently run darcs show contents
(with a long matcher) three times:
for i in seq 1 3; do
darcs show contents --match "hash
20080215012747-92b7f-46b20ea5a2f9ea5678b3f901f0818f8f61e9f97a.gz"
"src/allmydata/util/base32.py" &
done
The failure message I get is

If you think what you're trying to do is ok then
report this as a bug on the darcs-user list.

The attached script just shows which repository you need to darcs get to
reproduce this. Note that you may want to move your ~/.darcs/cache out
of the way first.
This needs somebody to investigate. Why might this be happening? What
can we do (roughly) to solve it?
This sort of thing sounds like it should affect anybody running
something like trac-darcs, so maybe it's good to mark this urgent?
