WARNING:
On MacOS 10.6 (at least up to 10.6.6), your network will
stop responding about 10 minutes after the first time you
start sshuttle, because of a MacOS kernel bug relating to
arp and the net.inet.ip.scopedroute sysctl. To fix it,
just switch your wireless off and on. Sshuttle makes the
kernel setting it changes permanent, so this won't happen
again, even after a reboot.
