Test suite hangs and never finishes successfully

[polotek]

When I run the test suite, it hangs and never finishes. I've got all of the dependencies installed, barring this #37. I assume the tests run with nose since it's in the requirements list. When I run nosetests I get 6 dots like it's starting to run tests, then it stops and hangs indefinitely. Not even a timeout. I've also tried running nosetests tests/ to limit it to the tests folder. That produced no change.
