Dr. Skippy,

 * As part of this change, I found an error in the union filesystem. In
 * union_copyup() (called when we need to copy a file from the lower layer to
 * the upper), we would lock the file we were going to copy, but only unlock
 * it if we successfully opened it. This change was not in the patches I sent
 * to tech-kern.

Do you think this might be the cause of the unionfs 'Locking against myself'
