Allocators have been a disappointment. I'll guess that if the library
working group were to do it over again, there would be quite a few people
arguing for no allocators parameters in the standard library
containers. Every addition parameter (when as complex a concept as
allocators) adds to user confusion. One alternative is to just let the
implementations do the right thing. The other is to fix allocators.
