It happens automatically, although not necessarily gracefully.

When the main thread terminates, the process dies.  What happens if you
simply let that happen?

Only if you have some need to make the main thread wait for all its child
threads to complete before terminating.  This might happen, for example, if
a child thread is responsible for writing a disk file and you want to
assure consistency of the data written.
