Or, better, do:

while(g_main_iteration(FALSE)); /* No body */

which skips the gtk wrappers around the glib main loop.
In 2.0, you'll want to do:

while(g_main_context_iteration(NULL, FALSE)); /* No body */

since g_main_context_iteration() is deprecated in 2.0 (the API changed
a bit when they added support for multiple main loops).
