- * Call the stack overflow hook function if the stack of the task being swapped
- * out is currently overflowed, or looks like it might have overflowed in the
- * past.
- *
- * Setting configCHECK_FOR_STACK_OVERFLOW to 1 will cause the macro to check
- * the current stack state only - comparing the current top of stack value to
- * the stack limit. Setting configCHECK_FOR_STACK_OVERFLOW to greater than 1
- * will also cause the last few stack bytes to be checked to ensure the value
- * to which the bytes were set when the task was created have not been
- * overwritten. Note this second test does not guarantee that an overflowed
- * stack will always be recognised.
