It would also be useful to know what matplotlib version and backend you are using, and what version of ipython. For what its worth, I use ipython -pylab with svn/bzr ipython and the qt4agg backend on a multicore machine without any problems. If you can, I suggest trying the development branch of ipython (not ipython1), there was some improvement to the threading code recently, although I don't know if it would relate to the problem you reported.
