-   to a core file.  This gives a debugger enough information to
-   reconstruct (and debug) the virtual address space at the time of
-   the coredump.
-   Pyramids have an distinct fourth region of the virtual address
-   space, in which the contents of the windowed registers are stacked
-   in fixed-size frames.  Pyramid refer to this region as the control
-   stack.  Each call (or trap) automatically allocates a new register
-   frame; each return deallocates the current frame and restores the
-   windowed registers to their values before the call.
