not true for glib functions. Actually you only need to guard functions
that call GDK functions. If you are not sure, you are on the safe side 
by obtaining the lock for all gtk_* and gdk_* called from your threads.

glib itself is thread-safe, but of course you need to locking if two
threads access the same data structures (a GHashTable for example).


Salut, Sven
