f53a5e569d Configuring awl pool to give give up and scan an entire segment after 200 single access hits, after observing open dylan bootstrap on ubuntu 12 hammering the table and making no progress. 
AWL pool no longer tries a single access if the trace band has reached rank WEAK, since it doesn't need to.
