Get with X-Newest leads to errors in object server

[Constantine Peresypkin]

When getting an object larger than 64k (default chunk size) with the X-Newest header set
proxy server may improperly close the connection to all object servers which had an "older" file replica
In my case it happens each time

I'm attaching here a patch for proxy server.
Patch also has a small test which can be considered a repro for the problem.

Thanks for the patch! I'll look into transferring this to a gerrit review patch set tomorrow.

I see that Darrel is not happy with the test.
That's good, because I was also not so happy with it. It was not catching SIGPIPE (it's not an exception).
Anyway, I'm attaching here a patch with improved test that should properly handle SIGPIPE and fail correctly.
