Subject: r24765: added a RAW-HOLD-OPLOCK test. This is a manual test, meant to
 be used to test the interaction of oplocks with local filesystem or NFS
 access. You start it, then manually access the 4 files via another mechanism
 (such as a shell) and see what oplock breaks you get (This used to be commit
 4c3e4564260e55434a54a013051db609c92cabe8)
