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.
