digitalmars.D.learn - Is core.thread.osthread.Thread thread-safe?

I want to do this:

import core.thread.osthread : Thread;

void main() {
     shared(Thread) thread1 = new Thread({
         // Do stuff for a while...
     });

     auto thread2 = new Thread({
        // ...
        if(thread1.isRunning)
            // Do a thing.
        else
            // Do a different thing.
        // ...
    });

     auto thread3 = new Thread({
        // ...
        if(thread1.isRunning)
            // Do a thing.
        else
            // Do a different thing.
        // ...
    });
}

However, I get various compile-time errors when I try to write 
code like this because nothing in the Thread API is annotated 
`shared`. Are Thread objects really not thread-safe, and if so 
what is the correct way to synchronize access to one?

(The documentation for core.thread is broken right now, with dead 
links and at least one reference to an example that doesn't 
actually appear anywhere on the page.)

I don't personally use the shared modifier here, you can just 
access stuff without it like in the source it does thigns like 
atomicLoad so like i think it is ok but idk eally.

Yes, yours are much better - they have a bunch of content which 
is mysteriously missing from the official docs build. Thanks!
