We currently lack a sysctl interface to get finer-grained
process info.  I think KERN_PROC_THREADS (or whatever) should
be added as a flag to the sysctl, so that you can 'or' it
in to 'op' of kvm_getprocs().  You would need some kernel
changes to support it too.  I can look at it when I get
a chance.
