Workaround for infinite recursion crash
* FreeBSD crashes on infinite recursion rather than throwing a stack
overflow because the stack address of the fault is in the page below
the guard area. Workaround this by rounding down the fault address to
the nearest page boundary. Investigation is still under way into what
may be causing this but this appears to prevent it in simple test cases.
