As far as I can tell, it's not possible to create a class derived from Thread
and have it apply to the main thread.  This is because the "static void
thread_init()" function internally does a "new Thread()".  Thus, if I want to
create a derived class, I must duplicate this function in it's entirety rather
than just call it as part of the derived "thread_init".

How about having the existing class take a single Thread parameter that
defaults to "null" and only allocate a new object if "null" is received.

public static void thread_init(Thread t = null)
{
    if (t is null) {
        t = new Thread();
    }

    ...
}


I would then have my derived thread class define its own function like this...

public static void thread_init(MyThread t = null)
{
    if (t is null) {
        t = new MyThread();
    }

    Thread.thread_init(t);

    ...
}
