The GNU C Library has a mechanism to override this, driven by
environment variables, and a wrapper utility callet "stdbuf" which
uses the environment variables to tell a child process what buffering
discipline to use for stdin, stdour or stderr.

Now I understand what's going on (back then I've come to conclusions and
called names (AKA -- I'd been pissed off by 9 out of 12);  I was
wrong).  But variables?  Neither stdbuf(1) nor setbuf(3) give any
directions.  What should I read?
