It happens for any option which causes the sysctl to return no
processes to libkvm. (Try ps -p 100000). I think the following
patch should fix the problem.
(Kirk changed the way the struct proc size was checked, and the
old way happened to work OK if no data was returned. Kirk, should
I go ahead and commit this?)
