It's not; the old code was just wrong. If you want to "revert" then
make an explicit option to ignore the convergence failure since thats
what the buggy old code essentially did. However I'm told that the
problem only happens when you erroneously specify a bitrate that
cannot be met given the qmin/etc. params.
