AFAIK, Intel does use lock-free techniques heavily in its thread
library to wasting time on concurrency primitives, so I do not think
the current implementation of your library would compare favorably
with it. On the other hand, I do not see why the same techniques
couldn't be applied equally to your library.

You need to be an expert on lock free programming (which I am not) to
take advantage of it, and experts in this area are still uncommon, so
you may have an hard time optimizing your library.
