[tahoe-dev] odd determination of unhealthy

[Greg Troxel]

I did a 'tahoe --check --raw' on my main directory in the pubgrid, and
got an odd report: the object is 'unhealthy', even though all 10 shares
are present, plus two leftover shares of a previous version.  I would
call that healthy with some stale bits in need of garbage collection,
but maybe I don't get it.

Another oddity is that running check on another client resulted in
seeing very few shares.  Both clients have real IP addresses.  But, the
one that saw only 4 shares is running (w/o storage) on a machine that
also runs a storage node.  Is it expected that one can run a client and
a storage node on one machine at the same time without problems?
