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.
