Intermittent failure of this test could be due to
insufficient time elapsing between either the local
and remote db's being created or during the
debug_timing calls. This patch forces greater timestamp
separation and forces debug_timing to always log timings.
Also add message to the failign assertion so if this does
fail again we get some clue as to why.
