fix deadlock in filePool logger. The deadlock was due to pages being evicted before Tupdate() released the log entry for writeback. Now, we track another timestamp, so that Tupdate() starts with something analogous to a writelock, and downgrades it to a readlock before pinning pages, and invoking callbacks

stop gratuitiously forcing the log to disk each time it is read (which was causing Tabort() to run extremely slowly). Also, add a "tryflush()" method to ringbuffer.
