The test case task-detach-6 started hanging with this revision though quite
infrequently (averaging one hang in every thousand runs or so). It hangs on
powerpc64 both LE and BE though it seems to happen more frequently on BE.
Here's an example of one that was hung for over 7 minutes. I first noticed
when our auto tester had hung for several days.
