It seems to improve performance slightly, but not that much. It's still
slower than the single-threaded version. Then again, the tests that I'm
running aren't that big (they're actually pretty small), so the
difference in GC_malloc_many probably doesn't have much of a chance to
show up. I'll see if I can get some bigger tests.
