be6cc2c3e6 batch implicit write tracking
bolt performance leaves something to be desired; doing a single Put takes 10ms, about the same time
as batching thousands of them.

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.

cb665d07e0 fix transactional race during compaction
It is possible for an object to be written or recreated (and checked with Has)
after the mark completes and during the purge; if this happens we will purge
a live block.
