    ;;; Loading of the boot file may segfault if a library is
    ;;; loaded before its dependencies are loaded first.
    ;;;
    ;;; reason is that the base libraries are not a hierarchy of
    ;;; dependencies but rather an eco system in which every
    ;;; part depends on the other.
    ;;;
    ;;; For example, the printer may call error if it finds
    ;;;  an error (e.g. "not an output port"), while the error
    ;;;  procedure may call the printer to display the message.
    ;;;  This works fine as long as error does not itself cause
    ;;;  an error (which may lead to the infamous Error: Error: 
    ;;;  Error: Error: Error: Error: Error: Error: Error: ...).
