So ok, to recap, the hildon_gtk_window_take_screenshot only sends a DBUS message
to the window manager, but the application still is kind of locked
while taking the screenshot
(I notice a small slowness when taking the screenshot for the first time).

Anyway, a thread wouldn't help at all and as we now know it's also not needed.

I think the best would be to have a way to retrieve the screenshot path
so that we can check for it's existence before taking a new one (thus
we wouldn't be checking
it in a static path as we do now), instead of
hildon_gtk_window_take_screenshot checking for
its existence.
