Make it optional for kvm_getprocs() (and related sysctl) to return
thread information.
Add a KERN_PROC_SHOW_THREADS flag that has to be set in order to get the
thread info and make it off by default. This creates backwards compatibility
for applications that relied on a given size/number of items to be returned.
Modify ps(1) and top(1) accordingly.
Okay guenther@.
