TCP inflight limiting is supposed to guess the bandwidth-delay
product for a TCP connection and stop the window expanding much
above this. It's a pretty neat idea for DSL links that often have
huge buffers at the far end, where inflight limiting can prevent
delays to interactive traffic.
However, some of the guys I know that work on TCP dynamics reckon
that they can they can come up with situations where inflight
limiting will break. Unfortunately, I haven't had time to talk
this through with them. I guess you may have found one of those
situations ;-)
