WebbClock streaching is a trick that is supported by the Basic I2C Protocol. The Master must wait for the clock to rise above the 1 threshold before timing the bit. Hold the clock low and it waits. SMBus uses this behavior. Basic I2C does not consider it a feature. Since I2C has no timeouts the HW will wait forever. SMBus requires timeouts.
