I understood that most engines had a small "back channel" that when the thermostat was closed would allow a small amount of the coolant to circulate around the engine. This would even out the temperatures, and also allows the now-heated coolant to come in contact with the thermostat due to the minor circulation...

Or is that an old wives' tale?
