I remember Glauber once used the bind() callback to detect if cpuacct and
cpu are mounted together and if so do some optimization.

Then he gave up on it and just deprecated cpuacct, but then it was decided
that it can't be decprecated and removed as that will break userspace.

So mayber Glauber will want to use this callback again?
