Hi Itamar,

So, rushing in where, ahh, somebody else fears to tread, I've decided to
use wx and Twisted on a project. Any updates on this I should know
about? Anything I can help you with? I'm noticing my own cheesie hello
world (PythonCard's 'counter' example all cozy snuggly with wxreactor)
doesn't quit on a ctrl-c with Twisted 2.2.0 on Debian unstable -- not
really sure what that means, just thought I'd mention it.
