This is absolutely mysterious.... on my FreeBSD development machine, I
have httpd-2.0.45 installed locally, a local copy of the svn
repository, and the latest (0.22+) svn client/server code installed.
When I checkout via http://localhost, it's the same speed as always --
several files per second.

Yes, we need to pin down exactly what's causing this.
