""" Checks if a thread is attached to the JVM.
Python automatically attaches threads when a Java method is called.
This creates a resource in Java for the Python thread. This method
can be used to check if a Python thread is currently attached so that
it can be disconnected prior to thread termination to prevent leaks.
Returns:
True if the thread is attached to the JVM, False if the thread is
not attached or the JVM is not running.
