Guys, is it *really* worth it to do all these crazy games?

How bad is it to just always use the async freeing, instead of this
clearly very fragile crazy direct-freeing-with-serious-locking-issues

Sure, even ioc_release_fn() isn't trivial wrt lock handling, but at
least it doesn't have to play these *insane* games with recursive

And if workqueues are too expensive, what saner alternatives might
there be? This code really is insane.
