In MacWorld page 277 -the article about aux... it says... The operating system will simulaneously support multiple UNIX applications and an unlimited number of UNIX scripts, but it will not offer true multitasking. What does this mean? Isn't A/UX unix? Why no multitasking? ira bye Ira Lee iradx7@pawl.rpi.edu ira@iear.arts.rpi.edu (518) 276-IRAS (718) 279-4814

Isn't A/UX unix? Why no multitasking? 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.
