<AWT Dev> [8] Review request for: 7123957: Switch of Gnome theme ends up deadlocked in GTKEngine.native_switch_theme

[Dmitry Cherepanov]

Here's a patch for the deadlock in GTKEngine.native_switch_theme

Bug report - http://bugs.sun.com/view_bug.do?bug_id=7123957

The fix partially reverts the changes for 6913179 [1] so that we don't 
wrap 'g_main_context_iteration' with 
'gdk_threads_enter'/'gdk_threads_exit' as 'g_main_context_iteration' 
takes care of locks (GTK lock functions aren't reentrant and try to get 
lock again causing dealock).

Webrev - http://cr.openjdk.java.net/~dcherepanov/7123957/webrev.0/

Thanks,
Dmitry
