That's a nasty problem.  See
http://sebulba.wikispaces.com/recipe+thread2 for info, and IPython
implements that trick in Shell.py, look for HAS_CTYPES in there and
see the signal handlers that are in that section.

It's never 100% reliable, but the addition of this trick did help a
lot for -pylab.  I don't know if it will do the trick for you.
