Note that temporary files are often creat()ed and then unlink()ed, leaving the open file descriptor as the last reference. You should probably run 'lsof' or similar tool. On my laptop at the moment: lsof -n | grep dele cardmgr 2207 root 3u CHR 254,0 5556 /dev/cm-2123-2 (deleted) cardmgr 2207 root 4u CHR 254,1 5559 /dev/cm-2123-5 (deleted) cardmgr 2207 root 5u CHR 254,2 5562 /dev/cm-2123-8 (deleted) exmh 7142 valdis 10u REG 0,16 0 74035 /tmp/tclfG25oV (deleted) gconfd-2 7805 valdis 13wW REG 0,16 641 44735 /tmp/gconfd-valdis/lock/0t1115905590ut151063u967p7805r252866408k3219173544 (deleted) aspell 9481 valdis 2u REG 0,16 0 74035 /tmp/tclfG25oV (deleted) So there's 2 open but unlinked files on /tmp, and du and df will show up different values. (Note that exmh did an open() of a file, unlinked it, and then passed the open file descriptor to aspell as stdin - so that space will be reclaimed once *both* of those processes have done a close() on the file descriptor).
