No, no, I meant I wrote my own, which doesn't show this problem in the traces I've examined. But, it's all rolled up into a bunch of other congestion related stuff I'm still working on like SACK and, more importantly, Limited Transmit, exactly because all this stuff modifies and examines the same variables and so all the functionality has to be tested together to make sure no part breaks any other part.
