Without these fixes, iterating over a queryset within another iteration would cause the "outer" iteration to only return 100 results.

This PR also fixes #1086 where calling len(qs) mid-iteration would cause the same problem.

Thanks to @eli-b and @gordol for inspiration!

@touilleMan are you still involved with this project? If so, would you mind reviewing this? I noticed that you gave a thoughtful description of the problem in #1086 (comment).

@wojcikstefan I'm not very active on the project right now (working on my own mongo odm 😛 ) but I always love to give a hand !

The PR pretty elegant to me, it's all good 👍

Thanks @touilleMan! I want to check out umongo for my next project, but for now I'll just try to make MongoEngine faster and less buggy :)
