I've used this a lot when looking for leaks. Especially combined with other things like -hbdrag -hc, so I'd be sad to see it go. Without it, how do you find lag and drag?
On the other hand, the entire profiling system has been hard to use because of crashes (perhaps due to that thread-unsafety thing), but also because of lack of documentation, the fact that SCCs can drastically change the performance of the things they are trying to measure, and probably just personal incompetence. But that's not really directly relevant to -hb, except to say I'd rather fix it than delete it.
