Comment 2 Milian Wolff 2013-01-31 21:35:39 UTC

Git commit 7a521fc9699a8c257baebcdfdcb7e8fd4c361ecc by Milian Wolff.
Committed on 31/01/2013 at 22:33.
Pushed by mwolff into branch '4.5'.

Make CTestFindJob killable to ensure it gets stopped on shutdown.

This should be the proper fix for the crash-on-close bug that
was encountered quite often. I do not understand how to trigger it
on startup though - can someone try with this patch again?
