Currently #defined in make.conf. I got bitten by some ports that 
are ignoring values set in this file. 'World' is always made with 
the FD_SETSIZE=1024. I'm reluctant to hack the #include, but might.
256 seems unreasonably small these days.

I have caught _some_ of yours and dg's comments on this. My house 
has been burning down here for the past week, so I have not had 
time to digest it.  Interesting idea though.
