Phill, please add your allocator here https://godbolt.org/z/drEnYera1 and
report back, if that is OK to ask of you.

Please note the benchmarking infrastructure in use and allocator interface
so that it can be used as a template argument to std::vector. I might dare
to call that code: "realistic benchmarking".

Kind regards...
