it's useful to limit per process mem usage to prevent oom killer because we can't save if we get killed. overhaul diskpagecache to just use rdbcache. much simpler and faster, but disabled for now until debugged more. reduce min files to merge for crawlbot collections so they stay more tightly merged to conserve fds and mem. improved logDebugDisk msgs. overhauled File.cpp fd pool. now it is way faster and doesn't use any extra mem. much simpler too. although could be sped up a little by using a linked list, but probably is not significant enough to warrant doing right now. increase mem ptr table from 3M to 8M slots. should really make dynamic though. fix core from null msg20s[0]->m_r. only call attemptMergeAll once every 60 seconds really. do not attempt merge if already merging.
