-/* I've heard that sometimes automatic garbage collection can outperform
- * manual collection, so I briefly tried using the Boehm-Demers-Weiser GC
- * library. Both GMP and PBC support custom memory allocation routines so
- * incorporating the GC library is trivial.
- *
- * Automatic garbage collection appears to slow this program down a little,
- * even if only PBC collects automatically. (The case where PBC collects
- * manually but GMP collects automatically cannot be achieved with the GC
- * library because PBC objects point at GMP objects.)
- *
- * Perhaps specially-tailored memory allocation routines could shave off
- * some time, but one would have to thoroughly analyze PBC and GMP memory usage
- * patterns.
- *
- * Below is the commented-out code that collects garbage for PBC. Of course,
- * if you want to use it you must also tell the build system where to find
- * gc.h and to link with the GC library.
- *
- * Also, you may wish to write similar code for GMP (which I unfortunately
- * deleted before thinking that it might be useful for others).
- * Note GC_MALLOC_ATOMIC may be used for GMP since the mpz_t type does not
- * store pointers in the memory it allocates.
- *
- * The malloc and realloc functions should exit on failure but I didn't
- * bother since I was only seeing if GC could speed up this program.
