When running the ipython notebook under dmtcp (dmtcp_checkpoint ipython notebook), running system commands in a cell (e.g., !ls) hangs the kernel. Running the same command under the ipython console works as expected. Running the notebook without dmtcp works, as expected. This is also python 2.7.5 (anaconda).
I've also tested this with the 2.0-dev branch of ipython, with the same results

Also occurs with python3
still happening with latest pulls from both ipython and dmtcp...
