With this, and with earlier commits, I have been running into situations where, with "ipython --pylab", keyboard input handling is unusably slow; each keypress triggers a burst of disk activity. It is not related to the number of commands entered in a given session; right now I have a session where it was almost impossible to edit the 5th command in the session. The previous command involved heavy computation (using mpl to generate a couple thousand png files), but no screen output and only moderate memory usage.
