This is great to hear. And thanks for the proposal. I'll get back to
you once I have had time to knock the ice myself a bit.

My main interest is not the upstreaming process that we are going
through right now, but more like post-upstreaming when the code needs to
be thrown at with arbitrary workloads. I think this will be a perfect
tool maturizing the code over time.
