Has anyone thought about the possibility (pros & cons) of making "printf(3)"
a SYSTEM CALL?  Think about it for a second (especially you PDP 11/70 and
lower primates).  Think about the resources you would save, viz.:

	Disk space (~4-5Kbytes)
	Primary memory (non-shared data and text <= ~4-5Kbytes)
	Compile time (AH! Not to have to load "printf.o" and "doprnt.o")

Well, now, Wilbur ... Think what it would cost:

	Kernel memory space (~4-5Kbytes again)
	More time spent user/kernel switching (for sure - groady to the max)
	Buffering problems ???

What can I say? It was just a thought.
