It's a limitation of S48's GC.  I just received the following report from
Kelsey.

    Yes.  Because the byte-code compiler doesn't do any free-variable
    analysis, every closure contains its complete lexical environment.
    For the first definition of SEARCH-STREAM the LP closure contains
    a pointer to the original lazy-list S, causing the heap to blow out.

    For Kali I wrote an additional compiler pass that does the necessary
    analysis and produces minimal closures.  The downside is that loading
    code takes over 50% longer.
