This looks good.
The same "thou shalt not do multiple volatile reads" applies to
"(r.queue == NULL) || (r.queue == ENQUEUED)" now. Also, continuing on
the micro-optimization spree, you might want to use bitwise |, not
logical ||, saving a branch. Both things are optional though, it does
not hurt much at this point due to the synchronization, and we can
address these if/when we do the overhaul of that entire code.
