Nevertheless these are two different mechanisms and two different "caches"
we're talking about. What route a packet takes is decided by a completely
different system as what IP an address maps to. iptables also has a kind of
"cache" but that doesn't mean it has anything to with /etc/hosts or routing.
For routes, try "ip route flush table cache" (this is from memory, but it
was something like that).
For name services, nscd is the only thing i can think of that might cause
the behaviour you described (/etc/hosts change not taking immediate effect).
