To some extent, here, the issue is on Linus side and it's up to him (Hey
Linus ! still listening ?) to maybe be more proactive at giving an ack
or nack so that we can get a chance to do that final pass of ironing out
the mechanical bugs before we hit the main tree.

Let me add a little bit more background to my reasoning here and why I
think having this integration testing step is so valuable...

It all boils down to bisection and having a bisectable tree.

I think you are way too concentrated on this particular incident, 
and you are generalizing it into something that is not so in 
practice.

Even in this particular case, there's just 3 other commit points in 
the Git tree between commit 8a1ca8c (the breakage on PowerPC) and 
e14112d (the fix). We'll have up to 10,000 commits.

I bisect on an almost daily basis, and i'm not seeing unreasonable 
problems.
