      Description

      As Jesper Damkjaer reported in this post:

      http://fedora-commons.1317035.n2.nabble.com/fcrepo-dev-Synchronization-on-getIngestWriter-in-DefaultDOManager-tc6972143.html

      DefaultDOManager.getIngestWriter seems unnecessarily synchronized. We suspect that removing the synchronized keyword might improve concurrent ingest throughput significantly.

      We should also add a test that tries to concurrently ingest multiple objects with the same PID. Fedora should fail such attempts.
