access datalist flags via atomic pointer access funcitons, instead of
Wed Nov 23 17:34:01 2005 Tim Janik <timj@imendio.com> * glib/gdataset.c: access datalist flags via atomic pointer access funcitons, instead of acquiring the dataset lock. this is faster and also matches the atomic pointer readouts in gdatalistprivate.h and direct pointer modifications required by gobject.c.
