A slightly older version of this code was tested by BDE and I. Also fixes a lockup situation when kva gets too fragmented. Remove the maxvmiobufspace variable and sysctl, they are no longer used. Also cleanup (remove) #if 0 sections from prior commits. This code is more of a hack, but presumably the whole buffer cache implementation is going to be rewritten in the next year so it's no big deal. END
