+So the second connection received the GET request, but did not respond to
+it, or its response was not received.
+
+Maybe try replaying the same protocol on the server manually. Eg:
+
+	ssh bids@rolando.cns -T git-annex-shell p2pstdio /inbox/BIDS/dbic/QA --debug ed495e60-f4c1-4a9b-86fd-0b3cec9689a6 --uuid 6384a551-a41d-4290-b186-9258befede9
+	VERSION 1
+	GET 0 sub-qa/ses-20161205/dwi/sub-qa_ses-20161205_acq-DTIX30Xp2Xs4_dwi.nii.gz SHA256E-s24797353--d1bb6541067f4ba3cdb6a698e2e6e7dbd483d8179007ebd2f2774d11972daf04.nii.gz
+
+If it doesn't reply with DATA, then it's something to do with that
+one particular key. If it does, the problem must involve concurrency or
+the ssh connection somehow.

+
+I have found one possible way this protocol trace could happen, although it seems
+unlikely to be the actual cause here.. But possibly. Dealt with it
+in [[!commit 0b053b96119c1a2d6c2d03ba7f98f032e89b8b66]] which would need
+to be deployed to the server side to test.
