But MacOS, and Windows =< 3, were not well designed systems in that

newsgroup recently.

The future was never like this!
Come to think of it, cooperative multitasking is
trivial, you can code
your own. It looks like this:
for {;;} { task1(); task2(); task3; /* etc */ }
and each task simply does stuff for a while, then returns when it has
nothing left to do or when it's time to give another task a shot at
the CPU. That sort of system is very simple and very reliable.
Anyone who's used a Macintosh before OS-X might want to disagree here.
