nit: I'm never sure what the prevailing wind for Chromium Python style is, but
this does look "different" than the other Python files (four space vs two space,
camel caps for methods, no docblocks, etc)

Please check with someone who has Python readability to review this.

Oops.
I forgot that Chromium style was different from pywebsocket.
