Ah, the press. Yes, it's unix. You get the usual assortment of
unix processes running (all those NFS and networking daemons),
BUT the Multifinder environment, into which one logs in, is
itself only a single process environment (due to the Mac OS
architecture). Multifinder does its own "timeslicing" within its
own single-process world.
If one of your *Mac* applications decides to hang or crash, you
end up logging out (or being forcibly logged out).
The rest of A/UX simply treats that dying session just like a
logged-in user who crashed and burned. You get another login
screen, login again, and it's like you rebooted the Mac OS.

Never eat prunes when you're famished.
My opinion is my own. My employer? They use a windsock and a fire extinguisher.
