    *vl-preprocess-clock*

    Artificial bound on preprocessor loops, for termination.

    This is a really big number and is a fixnum on CCL. If there is no loop, it is hard to imagine ever hitting this; each expansion of a legitimate macro will require some consing, so we will almost certainly run out of memory before running out of clock.
