UpdatesCountFilter::UpdatesCountFilter(): wrong initial m_updatesCount
value

I'm guessing the problem is that print statements made outside of the
main thread are causing UI updates when those should only happen in
the main thread. I tried working around it by overriding the
TextCtrl.write method:

        self.stdOut.__labWrite = self.stdOut.write
        self.stdOut.write = lambda *args:
wx.CallAfter(self.stdOut.__labWrite(*args))

but this results in massive error spew about NoneType not being
callable. Oddly this shows up in my stderr window just fine, but the
spew locks up the program and I can't copy&paste it.

So what's the proper way to capture stdout and stderr to a text control?
