210 + ~30 = ~240 - which is getting close to 255. Since select uses a  
fixed bit field to represent filenos there's an upper limit on the  
filenos you can select on. What does this print?

#include <sys/select.h>
#include <stdio.h>

int main( void ) {
     printf( "%d\n", FD_SETSIZE );
     return 0;
}
