OK, I will not MFC it.

Is it worthwhile to extend the xsocket to have padding so that in 11.x 
and beyond we can allow for some changes in the structure?

Another idea I had was to include a version number with the sysctl 
request so that we can send back versioned structures, let me know what 
you think about that.

The first idea will take not more than a few days for me to accomplish, 
the second (versioning the sysctl) probably a few more days than that.

thanks,
