I don't think it presents much of an issue, as the coolant in the block is circulating. By the time the thermostat starts cycling like that, the engine is up to temp, and the t-stat is keeping it there. On my Jeep, the upper rad hose stays stone cold until the coolant temp on the gauge hits about 180*, then the t-stat starts to open a little.
