Is this just using ftp(1), or other tests as well?

I discovered that even on a fast machine that my rate limiting
code had an observable impact on non-rate limited connections,
which is why I rolled-out the code for the latter case, but maybe
I missed something.

OTOH, it could be the IP cksum stuff mentioned elsewhere on this

(I'm always a bit concerned when people's benchmarks using ftp are
different, because I don't know if it's my changes or the kernel's :)
