It ain't that simple, though. And that won't solve a problem like this:

operapluginwrapper is now taking up 75% of my CPU time, spinning somewhere.
Doing a "lsof -p" on it shows this excerpt:

----
operaplug 15946 kenny   44u  IPv4             310496                UDP 192.168.126.122:46378->LOCALNET-GATEWAY:domain
operaplug 15946 kenny   45u  IPv4             310495                UDP 192.168.126.122:50187->LOCALNET-GATEWAY:domain
operaplug 15946 kenny   46u  IPv4             310499                UDP 192.168.126.122:60787->LOCALNET-GATEWAY:domain

operaplug 15946 kenny  174u  IPv4             310492                UDP 192.168.126.122:37282->LOCALNET-GATEWAY:domain
operaplug 15946 kenny  176u  IPv4             310506                UDP 192.168.126.122:50020->LOCALNET-GATEWAY:domain

Now, "LOCALNET-GATEWAY" is the DNS server of the place I was connected to
*at the previous network* ; you can't get there from where I'm plugged
into now, and another server is serving DNS entries where I am currently.

So, what do I do here?
