Interesting, I had been paranoid since it failed that one test, I don't
suppose you have any idea on how much performance is gained, Cnews even
with the stock stdio is peppy enough that I don't know if its really worth
the bother.

Right setuid(geteuid()) just plain will not work, it doesn't work on AIX
either, in fact I suspect the majority of systems will not. However, there
is no reason not to use spacefor, it really is a nice feature. It is just
that it is the most system-dependent aspect to the whole Cnews package.
It is quite simple to get it to work with ISC. Change line 54 of the script
to look as follows:

	df $arg | sed "s/.*://" | awk "BEGIN { nf = 1 ; nr = 1 }

Also, this should be based on the spacefor.sysv prototype. Having this script
really work can keep you from overflowing filesystems, so its really not
desireable to shortcircuit it.
