Just want to say that I'm excited about this.

No Idea. http://stackoverflow.com/questions/25874823/pyerr-checksignals-not-picking-up-signal. Hopefully someone knows. The alternative will be to increase the splits and not use fastcache for the slow tests.

@certik and I talked it through and I think the problem was that I wasn't checking the return value for _every_ call into the Python-C-API (i.e. I knew my argument...

Looks like there are still timeout errors even without fastcache https://travis-ci.org/sympy/sympy/jobs/36210280. Maybe this is actually fixed and travis doesn't do timeouts well

I'm tempted to just blame travis. I wonder if others have this issue with signals and travis?

But this particular timeout is the `No output for 10 minutes` kind when the slow tests have a default timeout of 180s. It could just be a fluke but it's...

Ah. I'll probably try to do some more involve testing on my local machine then and just ignore whatever happens on travis.

Does the error only occur in 3.5?

Interesting. I thought I fixed this with #21 but apparently not.

I'm afraid I can't reproduce this. Are you sure that's the right sympy commit: ``` bash $ git log --pretty=oneline -n 4 08a8d78c7876f3266c1714d32158791e14f17f1f Merge pull request #9996 from Newman101/Hyperfocal 097d994d56bcc48eba83dd2825808a4689f79a10...
