while the initial series might be rebased once or twice, beyond the 1-2 
days of initial integration and testing i dont think that's true, and 
i'm doing up to 3-4 bisections a day just fine, on an append-mostly 
tree.

if you have trouble turning a Git tree into a bisectable tree then your 
testing-fu is not strong enough ;-)

[ the only plausible danger is to architectures that are not used by 
  testers all that much (so that breakages can linger a lot longer 
  unnoticed) - but why should the other 99% of Linux users be put at a 
  disadvantage for them. ]
