the SDM power meter (among others) writes the power consumption of three phases in multiple steps. this change helps to prevent getTotalPower() reading intermediate values, e.g., reading a new value for phase 1 but old values for phase 2 and 3 since phase 2 is currently read. cache the values, and write them all at once, protected by a mutex, later. closes #732.
