I was not aware of that.  Thanks.  Do you have a URL handy?

In any event, that is the part of the problem which I think falls
into the realm of packagers and/or sysadmins; a patch for that
doesn't seem sensible, given how cpusets are implemented.  I did
figure we would want to add some documentation around it, though.
Do you agree that is worthwhile?
