Bug summary

Stem will crash if you try to close the window while it's processing. It's also very slow for what I would consider a relatively small number of data points. I'm using the code from Julia, but I was informed the problem is Matplotlib. See original discusion.

Code for reproduction

using PyPlot
stem(randn(32768))

Actual outcome

This will work if you wait about half a minute. If you interfere by trying to close the window, the application crashes (Julia in this case).

Matplotlib version

I don't know. I'm using the most recent version of PyPlot and PyCall in Julia 0.5. Conda installed Python 2.7.
