Well, I wouldn't *expect* a jail to be able to pull the process list
out of the kernel.  It seems like a terrible idea to allow in the
first place.  I can imagine a carefully limited interface for getting
some of that information out, but last I recall (and admittedly that's
a pretty rusty memory), those programs dove directly into kernel data
structures.
