Oh, who knew. So if you set the timeout to 10s then it will kill
transfers at 10 seconds?

I could try patching the version string to 3.0.2 or do you mean there
is some change in 3.0.2 that attempts to make more happiness?
:-P none of this is very intuitive. So far I've bumped the timeout and
so all I can pray is that
 1) clients have enough bandwidth to complete any file they are
interested in within the timeout, and
 2) noone thinks of slowl0ris'ing me considering my whacky timeout value

:-P 0K
