Looking at rt.rs:

  sys::stack_overflow::init();

I probably don't know what this function does, because my initial guess is not very comforting. :)

It initializes stack overflow handling. You can read about what that means here, for Unix:

Just don't call sys::stack_overflow::exploit(); and you will be fine.

Ha! That's for handling one, but that's pretty funny.
