When force syncing, we sporadically hit this error (sometimes it works just fine, even on the same node):

12:14:17 p4 sync -q d:\myBuild/...#none
{{12:14:17 }}
{{12:14:17 }}
12:14:17 ... rm -rf d:\myBuild
{{12:14:17 }}
12:15:16 P4 Task: attempt: 1
12:15:19 P4 Task: failed: java.io.IOException: Failed to list contents of d:\myBuild\src\Tools\Python\2.7.13\mac\Python.framework\Versions\2.7\Headers

Note that this file is a symlink on a Windows machine (not sure if that's relevant).

Also note that the entire workspace is empty after the failure, with the exception of this one file.
