- Don't activate the Xt pump when not needed; it's not for most commonly used plugins - Don't use our glib pump's timer when Qt's glib event loop is on anyway. This doesn't cover 100% of situations, and doesn't really explain why QT_NO_GLIB works better for some people (never saw this particular case myself), but it should cover the "nspluginviewer wakes up a lot and uses a few% of cpu" case for most people. Hopefully. CCBUG: 182869 I am thinking off holding of on backporting this till 4.4.1, though.... svn path=/trunk/KDE/kdebase/apps/; revision=1075295
