Hello!

One more thought...

       3g. No need to tell Guile about much memory is allocated behind
           its back, e.g., with malloc(3).  This makes
           `scm_gc_register_collectable_memory ()' and friends (info
           "(guile) Memory Blocks") no-ops.

           It also means that BDW-GC has accurate information about heap
           usage, even in the presence of third party libraries that
           can't be instrumented to use `scm_gc_malloc ()' et al.,
           allowing it to make informed decisions.

Thanks,
