* 1) If a file is not opened with delete-on-close create options and
* the delete-on-close is set via Trans2SetFileInfo(SetDispositionInfo)
* using that open file handle, any subsequent open requests will fail
* with DELETE_PENDING.
*
* 2) If a file is opened with delete-on-close create options and the
* client attempts to unset delete-on-close via Trans2SetFileInfo
* (SetDispositionInfo) prior to the file close, any subsequent open
* requests will still fail with DELETE_PENDING after the file is closed.
*
* 3) If a file is opened with delete-on-close create options and that
* file handle (not the last open handle and the only file handle
* with delete-on-close set) is closed. Any subsequent open requests
* will fail with DELETE_PENDING. Unsetting delete-on-close via
* Trans2SetFileInfo(SetDispositionInfo) at this time will unset the
