Standalone server example scripts broken with mod_pywebsocket 0.7.7 and later

None of the example scripts (for instance, single_plot.py) work for me unless I 
use version 0.7.6 or older of mod_pywebsocket. With version 0.7.7 or later of 
mod_pywebsocket, I get a traceback that looks like this:

[2013-05-14 22:01:43,653] [WARNING] mplh5canvas.simple_server: 
'_StandaloneRequest' object has no attribute 'protocol'
[2013-05-14 22:01:43,654] [WARNING] mplh5canvas.simple_server: Traceback (most

AttributeError: '_StandaloneRequest' object has no attribute 'protocol'

It looks like mplh5canvas.simple_server is behind in some API changes in 
mod_pywebsocket.

This is on Mac OS 10.8.3 (Mountain Lion) and Python 2.7.3 installed from 
MacPorts. In fact, I came across this bug while preparing MacPorts packages for 
mplh5canvas and its dependencies mod_pywebsocket and netifaces.
