 From what I can tell we're getting a POLLHUP or POLLNVAL when we poll the
 data file descriptor.

 A POLLNVAL would indicate that the file descriptor has been closed. I
 don't see any way for this to happen without logging a "StartEncoding
 failed" message which I don't see in any of the logs.

 A POLLHUP could be seen any time the driver isn't sending data for
 whatever reason.

 I'm attaching a patch which will tell us which one we're really seeing.

 Please generate new backend logs with the latest master and this patch
