Unix provides uid and gid to act upon processes. Normally,
you have to either be the owner (or effective owner) or root to kill
a process. Mach provides this via capabilities so that anyone with the
proper capability could do it. 

Can anyone give me references or anecdotal evidence that Mach uses
capabilities to give a different look to permissions than Unix provides?
That is, do Mach users take advantage of the greater generality provided
by capabilities? thanks
