Cooperative multitasking is good enough for a lot of things,
even on processors much larger than a PIC.  Cisco's IOS is
still largely cooperative, for instance, despite images that
are 50+ Mbytes long running on 1GHz+ processors.  In my experience,
a lot of the "discipline" needed to do cooperative multitasking
simply moves to data structure locking when you go preemptive.
(which says, preemptive is easier when tasks don't share data
structures...)
