	"Suppose you set all your fd's of interest to be asynchronous
	and you handle the SIGIO instead of doing select?  Then it's
	signal vs.  signals instead of signals vs. select.  A blocking
	select would translate into a sigpause()."

From the fcntl(2) man page (4.2BSD vintage):

	"The asynchronous I/O facilities of FNDELAY and FASYNC are
	currently available only for tty operations."
