Hi,

this is an exact duplicate of issue #396 which was closed without getting a real solution.

I frequently get a very slow IPython session with a lot of IO activity triggered by cursor actions (up/dowm history and also moving left/right).
IOtop shows writes up to 50-60Mb/s.
This is always correlated to working interactivelly with matplotlib (memory use is not noticeably higher as usual). Simple stuff, no monster object or very complex figure.

I use Ipython 13.1 and matplotlib (1.2.0), but this problem is older than both these versions...
Running on Linux Mint 13 64 bit wit readline5 5.2.11 and readline6 6.2.8 (could it be a problem to have both libraries???)

Thanks a lot in advance... this is litterally a show stopper!
JF
