add simple refcounting scheme to concurrentSkipList.  This solves the
problem where a deleted node points to another deleted node, and we
only have a hazard pointer for the first node.

add hazard pointers for update using the smallest free slot first.  The
old method left a race condition, since hazard_scan stops at the first
null pointer.

7f332f85cc 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 2011-07-15 17:37:50 +00:00
