Have you tried to delete locally, instead of over NFS?

Maybe by deleting over SMB from a Windows machine, the file is not 
deleted but rather moved to a "Trash" folder on a different disk (which 
would explain the I/O)? (Same could happen with a Unix desktop, like KDE)

Have you tried the "unlink" command instead of "rm" ?
