Hmmm. Does POSIX specify that fork() is the process-creation mechanism? I
hope not... while the fork()-exec() pair is singularly elegant, it's not
implementable (without a massive number of kludges) in a wide variety of
operating systems: OS/9, VMS, RSX, AmigaOS, and in fact any O/S I can think
of off the top of my head other than UNIX.

While I'm here, what's the sentiment among C standards folks for some sort
of standard co-routine arrangement? It would not require any changes to
the language, just a few library routines: cocreate(), cocall(), codelete().
It should work on any machine without a strict stack segment (and C on such
a beast is going to have problems anyway).
