Yep. It's the queue starvation issue that someone else brought up (can't
remember who that was...). Basically, if you don't have some outstanding
command that will complete after you fail your queue_command() call then
there is no method of goosing the current holding queue in the mid layer.
It doesn't have a timer backup goose method as of yet.
