/* S_collect is called from scheme under the following conditions:
* 1. An attempt is made to allocate a small object and the ap is above
* the red line.
* 2. The current frame of the call is dead, so, upon return from S_collect,
* the caller returns to its caller.
* 3. The frame-pointer of the caller to S_collect is saved at
* pcb->stack_extent. No variables are live at that frame except for
* the return point (at *(pcb->stack_extent)).
* 4. S_collect must return a new ap (in pcb->allocation_pointer) that has
* at least 2 pages of memory free.
* 5. S_collect must also update pcb->allocaton_red_line to be 2 pages below
* the real end of heap.
* 6. S_collect should not move the stack.
