Hmmm ... you know, it might be useful if you could twist this knob via
   a sysctl (for example, if you're behind a firewall).


heh.


we discussed doing this with a sysctl, but we couldn't find a suitable
name for it  :-)  it's a property of at least tcp and udp but it _isn't_
a property of ip, so without splitting it into lots of little variables
(one for each protocol), there didn't appear to be a "neat" place for
it to fit.  you can just change the #define for now...
