Yes. (Or it was then -- there seems to be an update to 2.3.6 now.)

They were definitely not expiring on Fedora (after ~18 hours with
`positive-time-to-live hosts 3600' in nscd.conf). The cache files had
ancient modification times; I don't know whether that's an artefact of
the mmapping I see is used.
Sorry I can't check this on Debian, but it looks to me a risky option
to have on anyway.
