Without this, non-terminated backends were not properly
supported if they gave tiny responses or responded faster
than we could stream the response to the client.

This is necessary to support fast responses from some non-Rack
HTTP/1.0-only backend servers which rely on connection
termination to terminate responses.

Tested manually with a Perl PSGI application running under
"plackup".  Unlike Rack, the PSGI spec does not specify whether
the PSGI application or PSGI server should handle response
termination: git clone https://github.com/plack/psgi-specs.git
