I second that. I do not want to change structures anymore...
... and I do not think that adding ssthresh helps much. When
I'm interested in these values, I'm also interested in any change
of them. So you need some kind of logging infrastructure.
FreeBSD, for example, has such a infrastructure, but it is
system specific. Other OSes might have similar things.
