Something 'not right with your set-up; works for me (on a pair of HP ProBook
8470w running Ubuntu 12.04, patched with 'send-to-self'; connected back-to-back
via the motherboard ethernet port).

I've gotten this in TCP mode too, when using a -b bandwidth throttle. UDP uses
a throttle by default, so I'm guessing the problem is in the throttling/timer
code, probably on the server side, and not UDP related. Will look into it.
