Is it really problematic if an import is behind on the foreign branch
while it is being filled in, rather than being empty as is the case now?

Perhaps we could factor out some of that logic into a helper class that
is shared by the different fetcher implementations in foreign branch
plugins, fastexport/fastimport, etc. This sort of logic might be
specific to the target repository format, which may or may not need
regular repacking, flushing, etc.

Ian and I looked at bringing in one of the classes from fastimport that
handled batch imports into bzrlib, but we never got around to actually
writing the tests and proposing it for merging. 

Cheers,
