It should be possible to automatically allocate non-pods from a freelist.

Might I suggest turning this library into a general concurrent data
structures library?  Lock-free is great, but sometimes it's either not
available or is simply too slow outside of niche circumstances.  I
think a more general library that includes lock-free along with other
less-than-lock-free algorithms would be more useful to the majority of
developers.
