So the point of hammer_hashcache (as I recall) is to spin on updating a
file and checking the hashcache to make sure it really does wait an
appropriate amount of time to make sure that content has changed.

It isn't a very deterministic test, and it is a fairly long running one,
but I can agree with Robert that if there is a problem it may, in fact,
be genuine, and not just a testing artifact.

On the flip side, I don't think we use 'hashcache' since WT3, so it
isn't being exercised in day-to-day. (We've advised upgrading to
- --dirstate + since bzr 0.15.)
