//  This solution performs a timing attack on the fork system call. By monitoring the process closely
//  it is possible to discover where the fork likely happened. With some basic heuristics, it's possible
//  to infer where the wrong character is. With very minor brute force searching it becomes very easy
//  to find the password one letter at a time.
