those missing objects don't seem to ever get there, are they from an abandoned fork?

94efae419e reduce length of critical section 
Just the purge; the rest is not critical -- e.g. it's ok if we do some duplicate copies
to the coldstore, we'll have gc soon.

still in the hotstore.

6a3cbea790 treat Has as an implicit Write 
Rationale: the VM uses the Has check to avoid issuing a duplicate Write in the blockstore.
This means that live objects that would be otherwise written are not actually written, resulting
in the first write epoch being considered the write epoch.
