Should signal (software interrupt) handlers belong to a process or to a thread?
What will be an ideal response?
When a process experiences a signal, should any currently running thread handle it, or should a pre-arranged
thread handle it? And do threads have their own tables of signal handlers? There is no ’correct’ answer to these
questions. For example, it might be convenient for threads within a process to use their own SIGALARM
signal handlers. On the other hand, a process only needs one SIGINT handler.
