Sure. If somebody keeps the file opened it is not freed on
unlink() - only when the last process closes it. unlink() by itself is
trivial - remove the link from directory, update times on directory inode
and change the link counter on victim's inode. BFD. It's freeing the inode
that is long. And it happens only when the last reference to inode
disappears. Opened file descriptor counts as such reference.
