[IPython-dev] Notebook connection timeouts

Long-running notebooks will often become unresponsive and I see this 
from the server log:

```
...
WARNING:tornado.general:error on read
Traceback (most recent call last):
   File 
"/gpfs22/home/burnsss1/env6/lib/python2.7/site-packages/tornado/iostream.py", 
line 391, in _handle_read
     if self._read_to_buffer() == 0:
   File 
"/gpfs22/home/burnsss1/env6/lib/python2.7/site-packages/tornado/iostream.py", 
line 447, in _read_to_buffer
     chunk = self.read_from_fd()
   File 
"/gpfs22/home/burnsss1/env6/lib/python2.7/site-packages/tornado/iostream.py", 
line 911, in read_from_fd
     chunk = self.socket.read(self.read_chunk_size)
   File 
"/usr/local/python2/latest/x86_64/gcc46/nonet/lib/python2.7/ssl.py", 
line 151, in read
     return self._sslobj.read(len)
error: [Errno 110] Connection timed out
...
```

Is there a config in IPython I can set to help mitigate this? Would 2.0 
help?

64-bit linux, python 2.7.2...
pyzmq==13.1.0
Jinja2==2.7
ipython==1.1.0
tornado==3.1.1

Thanks for the insight!
