Ok, so my Python plugin can start an I/O bound thread in its
plugin_init routine and have that thread call a Geany function like
updating the status bar when the I/O completes?

Be very careful, both answers are wrong ;-)

And from your next post:

> I forgot to mention, for callbacks, I was thinking of using PyGTK/Gobject-introspection on the GeanyObject which has all the signals on it (IIR).  So plugins would do:

>   geany.object.connect('document-open', on_document_open_handler)

Does that allow on_document_open_handler() to be a bound member function?

PS I'm not intending to be negative about Geany Python plugins, great
idea, but from experience I think you will find some wrinkles in the
real world.
