PubSub doesn't do anything with, nor is aware of threads. This means that 
the subscriber will be called in whatever thread was active when the 
message was sent. It's not difficult to work around however, as the 
subscribed function could simply use wx.CallAfter to schedule a call to 
some other function to do the real work.
