Nick Craig-Wood 42f0963bf9 local: retry remove on Windows sharing violation error #2202
Before this change asynchronous closes in cmount could cause sharing
violations under Windows on Remove which manifest themselves
frequently as test failures.

This change lets the Remove be retried on a sharing violation under
Windows.
