FWIW, with the fflush() added after that sleep, and the fix to the
long long computation of sleep time to keep it from overflowing,
pg_autovacuum has been working flawlessly on my FreeBSD 4.9 + PG 7.4.0
production server. I'm just still playing with tuning pg_autovacuum
to keep it from vacuuming my busy tables *too* often.

Just a question: will my test program show negative sleep 'diff' on
your linux box? I can't imagine that it would give different results
than on freebsd.
