Mach has its own ps.  The problem is that it just dumps core.  I rebuilt it from inside the source, and it has some weird pathing issues, but it dumps core too.




At that point I kind of gave up.




One fun thing is searching the boot string reveals exactly one machine running this build.  Although I would imagine that they probably have nothing left of this..

`ps` is a little unhappy. Hmm. Wonder why.

I don't think those PIDs should be negative. :)
