Nothing! That's all good. :-)

All I wanted to say is that I think that it's a pity that
<sys/queue.h> provides macros that implement operations that can only
be implemented with a suboptimal time complexity. A good example is
SLIST_REMOVE(). In my opinion, it shouldn't exist in the first place.
As soon as you need it, you should have very likely used LIST_*()
instead.

It would be nice if we could at one point get rid of those bad macros,
but I guess I may be too optimistic about that.
