The original issue that I had with all of this is the fact that if the
current algorithm can't find an available pid, it just sits there
churning forever and hangs the machine. My original patch was really
just a very basic fix for that (see the 2.4 tree). This makes it far
more unlikely for us to max out, but if we do aren't we just going to
have the same trouble all over?

Thanks,
Paul Larson
