I replied to Andre in more detail since he seemed to be
unfamiliar with some of the details of Mach.  Still, I
think it is worth noting to the group as a whole that
the cost of task_create for a task with 1.6MB of memory
(including a 1MB array stored at program startup time)
is 1ms on a Decstation 3100 under Mach 3.0 (with all
memory inherited copy-on-write).
