It is safe to access a glib object (i.e. GObject) or data structure from
multiple threads the same way its safe to access/modify an integer or string -
as long as you protect the data from yourself simultainiously accessing it
from another thread (i.e. use GMutex and GCond).

If you are accessing data that belongs to GTK+ (i.e. widgets), then
you must share the gdk_threads_mutex with GTK+ (i.e. gdk_threads_enter/leave).
