Two things:

Firstly, time how long it takes the configured DNS servers to resolve
an invalid name like googlec.om; see how long it takes.
See if its even giving a reply!

Then I'd check these rules out:

> if (isInNet(host, "192.168.42.0", "255.255.255.0")) {return

.. etc;

as this causes the browser to do a DNS lookup. I haven't looked into
it to see whether DNS lookups are done for -each- of those isInNet()
or whether its cached (which you'd kind of hope!)
