Err, gee...
I flip to page B-5 of my 1986 Exec book, and there's the C code staring
back at me (albeit sideways).

CreatePort() does (or did):
	AllocSignal
	AllocMem a MsgPort
	Initialize MsgPort with passed name, pri, and signal, task, etc.
	AddPort if passed name is non-NULL (public port)
	NewList if private port
That's it!
