Doesn't buy you anything on some systems, either because they don't support
threads, or they have another malloc entirely.

In fact, this is fairly tied to glibc. If you don't have the glibc, it uses
its own malloc. And some systems may have another malloc, that works faster
than that specific malloc...

This is what I experienced on OpenBSD. fast-malloc is not any faster than
the default malloc, and it's even a bit slower.
