A few changes to deal with multi-user performance issues seen. this
brings us back roughly to 4.1 level performance, although this is still
far from optimal as we have seen in a number of cases. This change
1) puts a lower bound on buffer cache queues to prevent starvation
2) fixes the code which looks for a buffer to recycle
3) reduces the number of vnodes back to 4.1 levels to avoid complex
performance issues better addressed after 4.2
