Why is memory reclamation so important for lock-free algorithms?

I think it does fit that description, but for some reason none of the implementations I found were completely without atomic ops. They had at least barriers which aren't free on ARM.

wouldn't you need acquire/release barriers around your load and stores of your token (or alternatively acq/rel load/stores)? Otherwise your other operations won't be ordered with regard the epoch marked by the token.
