New issue 2335: Maximum recursion depth exceeded with coverage

Mark Williams:

Running Twisted's test suite with `coverage` (version 4.1) results in several `RuntimeError`s because the recursion depth's been exceeded.  See: https://travis-ci.org/twisted/twisted/jobs/140817070

I've been able to reliably reproduce the last `RuntimeError` (when `coverage` is trying to write out its data) locally on a PyPy built with `lldebug0`.  Attached should be a traceback from `stack.c:57`.  Having read #2200 I figured this would be helpful - please let me know if there's anything else you'd like.

I have similar tracebacks for similar `RuntimeError`s, but not the exact same ones as in the failed Travis CI build.  Please let me know if you'd like those as well.

Thanks for PyPy!
