Thanks for getting back to me, Martin. Do you read users@subversion, or
would you like me to keep CC'ing you?

Well, 26% is pretty significant (and those were repeatable measurements
to within .1s, by the way). But considering that the perl version was
so slow already that I was asked to remove it from the repo, it doesn't
really matter. We're a small enough team that we can get by on fear and
shame for a while, but it would be nice to be able to enforce this properly.

Ok, do you possibly have a few minutes to describe the changes you were
planning to make in a bit more detail, so that I can take a crack at
them myself? My python's quite rusty, but I'll try to get over my
irrational distaste for significant whitespace. :)

What's the failure mode, adding two files with clashing names in a
single revision? Or is there a more subtle failure mode I've missed?
