   That's an interesting idea. Hmmm....

   It's always been safe to use higher values. I don't know what purpose the
warning was supposed to serve (perhaps to protect against crazy people?).

   It means that your machine talks to lots of others and the routing table

this by lowering the timeout for these. It's not uncommon for the timeout to
be lowered to as low as 5 minutes on freefall.
