No. start_new_thread is for use with the "thread" module. The threading
module is a higher-level interface to that module. Basically you do this:
import threading
thread = threading.Thread(None, YourFunction)
thread.Start()

There are several methods, I usually use threading.Lock, threading.Condition,
threading.Event (see the docs) so that other parts of the program can check
if a thread is active.

Again, you can use a lock, condition or event to notify your program that
something has happened. Simply place the threaded code inside a try..except
and set the condition/event/lock in case of an exception.
If your thread is crashing all the time, I would try and find out why and fix
it rather than simply working around it.
