MemoryError in 2.2.0 in odd case: Can I reduce memory requirements?

[Maritza Mendez]

Hi, Martin.

Your observation about phones is certainly correct.  I would ask how this
scales on the bzr smartserver end of the wire.  If, say, four developers are
merging to/from four different branches [1] simultaneously, it seems like
the box running the bzr smartserver might thrash badly.

What do you expect?

[1] For simplicity, assume plain branches.  For complexity, assume four
branches in a shared repo.

Thanks
