Hi Eric,

no, I did not see that... it would have saved me some reverse
engineering time.

Yes, that was my second attempt too. My first one was to check for
the presence of the spin callback. I was using
g_main_context_find_source_by_user_data() with the instance as
user_data but I soon discovered the argument of that callback is
wrapped by gdk_threads_add_timeout() [1] [2], so I gave up.

That is really smart and dirty! Yes, the hackishness level is still
quite high.

Many thanks for the suggestions, really appreciated. It seems the
solution requires a macgyverism after all.

Ciao.
