Make sure you declare a GMainContext for your mainloop in your
tread and use the proper varients for creating GSources.

A GObject is in your programs data, your threads share the same
data - signal emmissions are a synchronous affair, no weird surprises,
when a gtk+ api is called, all related signal callbacks are executed
*before* the gtk+ api in question returns.
