All the other things aside, mount-time is interesting, but it's an
infrequent operation, at least in my world. I think we need something
that can be done runtime.
For anything with uptime, I don't think it's acceptable to wait until
the next mount to trim unused blocks.
But as long as the mechanism can be called either at mount time and/or
kicked off runtime somehow, I'm happy.
