    Problem Text
    This test may fail on implementations where RLIMIT_DATA is not
    enforced.

    The assertion first tries to lower the heap size by

    1. querying the current limits for RLIMIT_DATA:
    (** Our implementation returns RLIM_INFINITY for this resource.)

    getrlimit(RLIMIT_DATA, &save)


    2. Setting the current limit to the lower of the previous max
    and 4MB:

    heapsize.rlim_cur = save.rlim_max or 4MB (whichever is less)
    heapsize.rlim_max = save.rlim_max
    setrlimit(RLIMIT_DATA, &heapsize)
    (**this call to setrlimit() fails with EINVAL on our implementation.)


    The X/Open XPG4.2 standard for get/setrlimit says (3rd paragraph)
    "...If a call to getrlimit() returns RLIM_INFINITY for a resource,
    it means the implementation does not enforce limits on that
    resource. Specifying RLIM_INFINITY as any resource limit value
    on a successful call to setrlimit() inhibits enforcement of
    that resource limit."

    The standard does not detail what must happen if RLIM_INFINITY was
    specified as the resource limit and then setrlimit() attempts to
    alter the current or maximum limits. If only details what happens
    if the current and maximum limits are valid limits (i.e., not
    RLIM_INFINITY)
