Sad story about darcs show

So today I did what I have in my TODO for some time: make darcs-fast-export produce the fast-import stream on the fly, without a tmp working dir (that's how tailor and darcs2git works, and I think that's just ugly).

And the result? I thought this will be the trick that makes it a lot faster, compared to tailor and at the end it turns out that it slows it down about 3 times. :-(

Not counting speed issues, it's a huge cleanup:

 12 files changed, 34 insertions(+), 106 deletions(-)

Dunno what to do with it now. I'll try to poke the darcs devs, maybe they can optimize it a bit.

The sad fact is the comparision to git:

$ time darcs show contents --match "hash 20040523231834-97f81-2bca6242bec169bd01079378524a33e0310e0b65.gz" tailor.py >/dev/null
real    0m2.780s
$ time git show 451ae1176d56a579d3d7bd236fe7d7dd9df59326:tailor.py >/dev/null
