   Hm, this is starting to get old......


    I completly agree with the statement that Mac OS should have
   prementive multitasking.. Multifinder is a joke, they is no way to
   download from a modem while running another app. Here are some
   other problems.

.....See my previous post on this subject.


1. There is no way to set a task's inportance, each other the
   backgroud app's get equal time, except for the foreground app,
   witch can steel all of the cpu time if it wants too.

 You complety miss my point.  I never sugested that true
multitasking is going to be as fast as running a single proccess!  At
least Unix gives you a choise in setting which task is getting the
most cpu time. In multifinder, a simple "bad app" can bring
multifinder to a standstill.  I could write a little app that, if you ran
it in the foreground would bring your modem transfers to a dead
stop!

How about Scsi DMA?

Oh BTW,  I hope that the rumors that the '040 mac's will not support
scsi DMA are complete false.
