> We're getting a lot of false positives for successful SSH logins from a source that we recently blackholed. I suspect what's happening is that the retransmissions keep bumping up the size of the connection, until it crosses the threshold for a "successful" connection. 
> With the changes from BIT-730: Find and fix tcp sequence counting bugs, is it possible to improve the accuracy of the reported size?
