/**
 * @brief    Configuration of default stack sizes
 *
 * printf takes a pretty tortured route through the C lib
 * then via UHI syscall exception to end up at the UART
 * driver.
 *
 * When debugging timer code we get printfs on the idle threads
 * stack which can easily blow its limits.
 *
 * Note code must be compiled at -Os with these values, using -O0
 * you'll overflow these stacks.
 *
 * NO ISR stack is in use yet, interrupt use the current running stack
 * hence the big-ish default stack size.
