Here I think you claim a tenfold speedup on whatsnew. I'm actually
seeing a SIXTY-fold speedup, when comparing darcs-hs to Darcs 2.2.0 on
the darcs-hashedstorage repo, with no changes:
$ time for i in `seq 100`; do dist/build/darcs/darcs w >/dev/null; done
real user sys
0m3.334s 0m1.070s 0m1.080s
$ time for i in `seq 100`; do darcs w >/dev/null; done
real user sys
3m3.470s 0m58.460s 0m44.140s
Note that hard linking is working for me, which I believe means that the
latter case is affected by the bad-timestamps issue you mention. Oh,
and I'm using NFS.
