Original commit message from CVS:
2008-03-18  Andy Wingo  <wingo@pobox.com>

* sys/osxvideo/osxvideosink.m (gst_osx_video_sink_osxwindow_destroy)
(gst_osx_video_sink_osxwindow_new, cocoa_event_loop):
* sys/osxvideo/osxvideosink.h (struct _GstOSXVideoSink): If we
need to run an event loop, do so in a task instead of assuming
that there will be a GMainLoop. Fixes #523134.
