Yep.  It's amazingly fast.

That wouldn't satisfy britney2's "let's keep stuff in testing" mode neither,
because it expects the old ABI to remain in testing.

This one is correct.

So I think britney's rule that blocks out-of-date binaries to appear in testing
should be implemented in sat-britney.  It should be configurable to allow (libs
oldlibs) in, though.  Would that be possible?

Kind regards
