Indeed.  And I just found out that Leopard (10.5) dropped the entire kvm
which wasn't working to funky anyway.  I just made some implementation
of walking through all running processes for portage-utils' `qlop -c`
using sysctl calls -- the way to do it on Darwin, and that works even as
normal unprivileged user, so I guess we can just use that.

I was thinking of a wrapping process, but I only later realised that
this isn't working since many/most daemons fork into the background, so
you loose the control over it anyway.
