An unfortunate choice of words! Harmless is not how your average DBA

The files *are* truncated to zero bytes immediately. They're left
hanging as empty files until next checkpoint.
Ah, cool. So won't actually unlinking temp files be slower than just
leaving them for checkpointer to clear up offline? i.e. do we really
need the patch you just posted?
Dunno, maybe. I doubt it's significant either way.
