Log:
  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.
