Unfortunately because of the recent instrumentation and CheckpointStartLock patches this patch doesn't apply cleanly to CVS HEAD anymore. Could you fix the bitrot and send an updated patch, please?


The "Logging checkpoints and other slowdown causes" patch I submitted touches some of the same code as well, that's another possible merge coming depending on what order this all gets committed in. Running into what I dubbed perpetual checkpoints was one of the reasons I started logging timing information for the various portions of the checkpoint, to tell when it was bogged down with slow writes versus being held up in sync for various (possibly fixed with your CheckpointStartLock) issues.
