[IPython-dev] Notebook doesn't load with latest master

[Dave Hirschfeld]

The error I get is:

  File "c:\dev\code\ipython\IPython\frontend\html\notebook\notebookapp.py", line 
553, in init_signal
    signal.signal(signal.SIGUSR1, self._signal_info)
AttributeError: 'module' object has no attribute 'SIGUSR1'

Seems it may not be available on windows? See below for more detail...

Thanks,
Dave
