title: Is it possible to signal handler to survive after "exec"?
body: <p>I wrote a signal handler for a process, and fork() after that, the signal handler will be applied to both parent and child processes. If I replace the child process with "exec", the signal handler is no more.</p>
  
  <p>I know this happens because "exec" call will overwrite the child process address space with it's own.
  I just want to know if there is a way to make signal handler work even after "exec" call ?</p>
