This would have worked on my machine. RedHat seem to have done things to
the /proc interface and it would appear from previous postings that you
then have to run the sysctl command to make it take.
Anyone know if this is an incompatibility with the standard kernel, or is
this just some re-orthogonalisation of the commands?
