        * daemon/slave.c: Fix problem with PostSession
          script not always getting executed when user
          kills the Xserver with ctl-alt-backspace.
          This is caused because an xioerror is generated
          by whack clients and this xioerror needs to be
          ignored for PostSession to be processed.  This
          problem tended not to manifest in GDM 2.6
          because the introduction of the whack clients
          call made the xioerror get generated earlier.
          However, it was still a race condition and
          this fix ensures that the xioerror will not
          cause the slave to ever exit too early.
          Fixes bug #152906.  Patch provided by Jerry
