As in my previous post, you switch it to the poll reactor by importing and installing the poll reactor before the default reactor is imported and installed.  You can do this by adding these two lines:

    from twisted.internet import pollreactor

to the program anywhere before the default reactor is imported.  For example, you could add them before the "import sys" line.

Note that this code:

>     reactor.run()

is all at the class definition level, so it is executed when the class
is defined.  This means you are starting the reactor before the class
definition has even completed.  You probably don't want to do this.  All
the code after this point doesn't even get a chance to run until the
reactor stops.
