Original commit message from CVS: * testsuite/schedulers/143777-2.c: (main): * testsuite/schedulers/147713.c: (handoff_src), (handoff_sink), (main): * testsuite/schedulers/Makefile.am: Added cleanup code to testcase 143777-2. Added testcase to show bug 147713, does not really show the deadlock as I can't figure out how to trigger it, but it does demonstrate bad ordering in the scheduler.
