> This is related COUCHDB-2833.
> This was found investigating the failure of replication tests. Specifically couch_replicator_large_atts_tests, the {local, remote} sub-case.
> The test sets up push replications from local to remote.
> Replication workers  have more than 1 document larger than MAX_BULK_ATT_SIZE=64K.  They start pushing them to the target, using a keep-alive connection (default  for HTTP 1.1), the first few pipelined requests will go through using the same connection, then server will accept the first PUT to …/docid?edits=false, then return Connection:close and close the connection after the 201 Created result.  
> Server should not close request too early and instead keep it open longer.
