* In Windows a DeleteFile/RemoveDirectory is the sequence of the following:
* Create(FILE_OPEN)
* SetInformation(Disposition)
* Cleanup
* Close
*
* The FSD maintains a count of how many handles are currently open for a file. When the
* last handle is closed *and* the disposition flag is set the FSD sends us a Cleanup with
* the Delete flag set.
*
* Notice that when we receive a Cleanup with Delete set there can be no open handles other
* than ours. [Even if there is a concurrent Open of this file, the FSD will fail it with
* STATUS_DELETE_PENDING.] This means that we do not need to worry about the hard_remove
* FUSE option and can safely remove the file at this time.
