With the Boehm GC, memory that does not contain any pointers,
such as strings, bit-vectors, arrays of ints, and so forth,
can be allocated using GC_malloc_atomic() rather than GC_malloc().
If you use GC_malloc_atomic() to allocate data areas that will
not contain pointers, then the GC will not scan those data areas.
