I think that it is a memory error. I was trying to mention that on IRC
when I got a stack trace. I'm unsure why it switch from an error to a
full blown trace. Interestingly, I don't ever see the Bazaar process
map all the memory in the system. I think it must be trying to allocate
a bunch all at once when this error occurs.

I'm guessing it might be interesting to know about the individual packs
as well:

I'm guessing it's trying to combine a couple of them at the time.

Perhaps unrelated, but FYI information. I've got 4GB of RAM, no swap,
running amd64.
