  This is already pushed, but please consider breaking up context.py into a package in the near future - it's far too large to comprehend, and I think it'd help organization if we had each of the various file{ctx} types (mem, working, overlay) in their own file and then re-exported in mercurial/context/__init__.py (so no other code would have to change, and external-to-hg clients of memctx (of which there are many) could be ignorant of the move).
