Using epd-7.1-2 at my workplace, IPython master, and Cython 0.17.2
installed in ~/.local, I get the following using the Cython cell magic:


cdef int i():

    return 0

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/opt/lisa/os/epd-7.1.2/lib/python2.7/threading.py", line 552, in
  File "/u/wardefar/src/ipython/IPython/zmq/heartbeat.py", line 55, in run
    zmq.device(zmq.FORWARDER, self.socket, self.socket)
  File "device.pyx", line 55, in zmq.core.device.device
ZMQError: Interrupted system call

Then the kernel dies. Any idea what's going on?
