PyPy Metabug

[oberstet]

This ticket is to collect the currently remaining issues with PyPy when running Twisted trial.

The purpose is to group fails/errors and identify them to be Twisted or PyPy fault, so that individual tickets can be placed appropriately.

The goal is to make PyPy run Twisted trial fully green.
