Sometimes stack frames get surprisingly large

i sometimes had similar problems with my ext2/ext4 driver, and i found some tricks to help with that

first, compile your project with -fstack-usage
youll then get files like this:and boom, 640 bytes of stack for ext2_walk()!
that function can also recursively call itself when it encounters a symlink, so that would just wreck a pico stack

second, the kernel i'm using has stack guards, so basically, there is a magic number at the bottom of the stack, and it will check that at various times, and warn you when youve blown the stack
