When running any example, closing the window crashes PySoy and often puts the terminal it was run from into a no-echo state. This is clearly not intended and needs to be fixed.

Capture the window close event and gracefully ceise further rendering to it. More artful functionality may be called for in a later GCI task.

While working on this task you should join and remain in #PySoy on Freenode to get help, feedback, and guidance from mentors and other developers. Code updates which may affect your work are also announced here as they happen. This is especially important for this task as other GCI tasks may be worked on to modify the same class.

When you've done, commit your work and post the resulting changeset url to this task.
