/**
* @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.
