Are you aware that there is nothing to stop an application to use
a larger FD_SETSIZE if it so desires?  Just #define FD_SETSIZE xxx
before the #include <sys/types.h>, and everything will work as expected.
No need to generate a new kernel or something.

IMHO that's flexible enough to get the best of both worlds (i.e. space
savings in small applications vs. support for many connections in large
ones).

Ciao,
Wolfgang
