Jobs intermittently crash at the very last second with:

10:02:14 [xUnit] [ERROR] - The plugin hasn't been performed correctly: remote file operation failed: <workspace> at hudson.remoting.Channel@5b65f425:<node>: java.io.StreamCorruptedException: invalid handle value: 007E7263

No other log messages are created by the xUnitService Log recorder. I eliminated the XML content as the culprit by copying XMLs from a failed job onto a Windows 8.1 node and having a job parse them 20-30 times with no reproduction.

We occasionally see a much more descriptive crash, I'm not sure if it's related:

I marked this crash as "Major" instead of "Critical" because we only see this 25~50% of the time depending on planetary alignment.
