>Description:
I write the code like this:

-------------------------------------------
#include <stdio.h>
#include <signal.h>
#include <stdlib.h>

int main(){
  while(1){
     system("./a.out");
     signal(main(),SIG_IGN);
  }
  return 0;
}
-------------------------------------------

When "gcc -Wall ./test.c" and "./a.out"&#65292;the system will be more and more slowly!
after about 1 minute,the system will be no-respond besides do a switch  
 of tty!  
Is there a way to prevent the circs when I system this code?!
