And here's a more generic one that is 10x faster for straight allocations.

Anyway my point being that apparently the rebind oddity has been removed
from the C++20 standards but not from my system headers... So perhaps
adding a similar ultra fast allocator such as this one into the stdlib
would be constructive.
