> Please answer this question. Under what circumstances can a signal handler interrupt a blocking system call in a thread that is not the main thread?

There is no guarantee that the signal handler is called in the main
thread. On FreeBSD, if I remember correctly, it is called in a random

You can control which thread gets the signal using
signal.pthread_sigmask() (block signals in other threads) and
signal.pthread_kill() (send a signal a specific thread).
