Comment 6 for bug 256757

I've decided to block 1.6-final on fixing this bug.
I'm not strictly concerned about the memory consumption (it is a problem, but not the most serious one). The general problem is the knit => pack fetching code is highly unoptimized, and the resultant pack repository is grossly bloated. And 'bzr pack' doesn't know (yet) how to re-optimize at the text-level. So you end up with a very sub-optimal result, and no way to improve it.
