It may work with programs under normal conditions but are the queues 
guaranteed to work with thread sychronization and other non-simple 
conditions? I'd think that the FreeBSD queue is closer to that.

Plus the FreeBSD Queue's API is simple and the maintainer doesn't have 
to peruse another set of source looking for the required function / 
method they need.

Furthermore, it's a requirement made by style(9) to use methods that 
aren't rolled by the implementor :).

Just a few thoughts.
