... and slow.  I mean *really* slow.  I mean, really truly HORRIBLY
slow.  I mean, if you think the city buses are slow. . . .

Why not, instead, add a `setvbuf(stdout, (char *)NULL, _IOFBF)' to
main, and then (since tty output will no longer be line buffered, being
efficient instead) add fflush() calls whenever you want the output to
be visible?  I have done it; it is not hard; it makes programs that
produce much output go much faster.
