Threads and main-loops

[Russell Shaw <rjshaw netspace net au>]

Hi,

If i make multiple loops with:

  GMainLoop *loop1=g_main_loop_new(context1,TRUE);
  GMainLoop *loop2=g_main_loop_new(context2,TRUE);
  GMainLoop *loop3=g_main_loop_new(context3,TRUE);
  g_main_loop_run(loop1);
  g_main_loop_run(loop2);
  g_main_loop_run(loop3);

Are all these running in a single gtk thread? If so, can their
callbacks call GUI widgets without thread-locking problems?
