I reverted Helge's patch and still get the same fault, so it didn't
introduce the problem.

Prior to 2.6.33, I was running 2.6.31.12 with essentially the same config.
The libc6 update to 2.10.2-6 changed things on the c3750.  Prior to the
update, expect would hang several times running the acats testsuite.  After
the update, this was fixed.  However, the above problem was introduced,
or became more frequent.

I have the feeling that Helge's patch helps (possible resolves) the
minifail bug.
