We do it a different way.  Our news comes in via nntp, active receive
(ie, we reach out and take it rather than their reaching out and giving
it to us).  We do hourly df commands and shut down the nntp program
which does news receiving when the usage figure hits 91%.  (It also
sends mail to usenet, so I can take whatever action seems appropriate,
and it also turns nntp back on when the usage figure goes back to 89%
or lower.)

(By the way, the nntpxfer program in the nntp 1.5 distribution is
incredibly inefficient.  Don't run it verbatim unless you like doing
one syscall per byte of news transferred.)
