Comment 7 Mark Wielaard 2008-03-13 22:04:02 UTC 
frysk.proc.TestRefresh has been renamed to frysk.proc.live.TestRefresh
All those tests pass now:

./TestRunner frysk.proc.live.TestRefresh
Running testRepeatedHostRefresh(frysk.proc.live.TestRefresh) ...PASS
Running testProcAdditionAndRemoval(frysk.proc.live.TestRefresh) ...PASS
Running testDaemonAdditionAndRemoval(frysk.proc.live.TestRefresh) ...PASS
Running testParentChild(frysk.proc.live.TestRefresh) ...PASS
Running testRefreshDaemon(frysk.proc.live.TestRefresh) ...PASS
Running testRefreshZombie(frysk.proc.live.TestRefresh) ...PASS
Running testUnattachedSingleExec(frysk.proc.live.TestRefresh) ...PASS

Time: 0.607

OK (7 tests)

So we can probably close this one.
