Change Details

I tested by running several buildworlds while I counted calls to the functions and cycles consumed by each. However, the test does not invoke vm_pageout_cluster, so I have nothing to report there. The results for collect_flush builds ``` Original: calls cycles/call collect_flush: 27932 211996.08194901905 collect_flush: 27929 251115.502560063 collect_flush: 27928 241602.81674305355 collect_flush: 27928 251525.5270338012 Modified: collect_flush: 27930 245027.55209452202 collect_flush: 27929 218708.71560027212 collect_flush: 27935 216557.6463576159 collect_flush: 27928 245812.133772558 ``` I ran the same performance tests again, this time with 8 buildworlds each.
