Bug report

input() blocks any rendering and event handling.

Code for reproduction

Lasso Selector Demo

I ran the code with python, ipython from console and ipython from Spyder 3.2.4 (fails in these three cases).

Actual outcome

The matplotlib window is not rendered and does not respond.

Expected outcome

The matplotlib window should be rendered and allow a lasso selection.

Remark: if the code from input() (included) is removed, the rendering and the lasso selection work as expected.
