For asynchronous I mean that local notification are not in sync with
global notifications (say "not in chronological order" if you like).
I understand that the name fusion_reactor_sync() is a bit odd, but I
couldn't find a better name for what it does
(fusion_recator_set_chronological()!? It doesn't sound good..).

I made the change because with the notification dispatched by "Fusion
Dispatch", the resizement takes more time to be notified, therefore
the IDirectFBSurface may still use outdated information.
Indeed, in the bug I explained in the log, the IDirectFBSurface is still
using the old clipping region when it issues the blit, thus the
destination rectangle exceeds the surface's size.
Change what you whant but at least surface's notifications should be
dispatched immediatly (to local reactions) to avoid these kind of bugs.
