This is a Tier2 failure so I'm starting this bug at P3.

I have a vague memory of a recent timeout being tracked
down to a Mac with really slow HDDs... Perhaps that's
the case here.

In any case, if this is a disk I/O intensive test, then perhaps
the default timeout value should be 180 instead of 120.
With the default timeout factor 4 that would give us 12 minutes
instead of 8 minutes.
