The minimum stack for Cortex-m does seem quite high - evidently the worst case
for interrupt nesting can affect things badly.
However other architectures do consider the minimum to be a, er, more minimal
minimum (if you see what I mean). So in practice I would add on maybe
4*CYGNUM_HAL_STACK_FRAME_SIZE, and hopefully that won't make things too large
on Kinetis.
