Making printf a system call is the worst idea I have heard yet.
The Unix system was designed along the principle of having the kernel,
provide only those services which are necessary.  Why not make the shell
a system call, and how about all the other library routines!

Actually, there is something that can be done about this.  Why not make the
library routines available as common shareable text pages.  This would
reduce the disk/memory load of the routines without inviting the do everything
in the kernal method so popular with DEC operating systems.
