test bench::treiber_get_put   ... bench:          95 ns/iter (+/- 1)

Motivation

I needed a very fast way to reuse allocations across multiple threads, potentially optimizing single threaded use over multithreaded use.

Future work

The current implementation uses a spin lock, which assumes there is very little contention.
