Orphans are files that were deleted while they were still held open by a process. POSIX semantics requires that the file data is still readable by the process, but that the file's hardlink(s) are no longer visible -- so there's no way of finding the file again by "normal" methods. Once the process closes the file, it is unlinked. Thank you very much.  Is there a way to suppress these messages about orphaned files?  I'd still like to see messages if something goes wrong, just not so much the orphaned files...
