The latter. It writes a clean swap.state based on the object Squid knows
is there. (it keeps all this information in memory while running,
therefore the memory usage by number of objects..).

Having a reasonably clean swap.state means faster rebuild on restart.

No. It just dumps the in-memory cache index to disk in a clean go,
truncating the swap.state journal file.

Don't remember exactly what this option did unfortunately. Was quite
long ago...
