that bit looks strange why is that kind of access needed?
There was a problem hiding this comment.
It fails on PY2 because fp is not a real file object, it is a _TemporaryFile (or something like that). In PY3 just passing fp to marshal.dump works.
It is probably possible to use marshal.dump(co, fp.file) in both Python 2 and 3, but I prefer to separate those cases so when the time comes around to drop Python 2 it is clear that we can keep the "cleaner" version.

@nicoddemus please rebase, then i'll merge ^^ |
This uses of the `atomicwrites` library. This is very hard to create a reliable test for. Fix pytest-dev#3008
