[pypy-dev] "import signal" fails when running PyPy interpreted

[Stefan Behnel]

Hi,

I get an ImportError when trying to import the "signal" module in an
interpreted PyPy (latest source checkout):

"""

Any ideas what's broken here?

I noticed this when trying to run a test from Cython's test suite in an
interpreted PyPy, and unittest failed to "import signal".
