A real part of the problem here is that the Linux doesn't have a full
TCP testing suite and doesn't have build checking to check for
regressions in TCP variants. As I understand the only thing tested in
nightly builds is throughput for the default TCP.

Stephen Hemminger has done some work on TCP Probes but this is where I
think real progress could be made in improving Linux TCP. I may get
around to doing this myself at some point in my research but would
welcome other people doing it also!
