Assuming there is no coding error in your program which causes an event
in the main loop to block (including a blocking g_idle_add() callback),
use g_idle_add_full() and give the callback a higher priority in the
event queue to put it ahead of the other events.

G_PRIORITY_HIGH will even put it above any GDK drawing functions (not
to be recommended though).
