If you're using D 2.0 then that shouldn't even compile.  In fact, 
std.thread doesn't exist any longer.  Try:

module Test;

import core.thread;
import std.stdio;

class DerivedThread : Thread {
     this() {
         super(&run);
     }

private:
     void run() {
         writefln( "Derived thread running." );
     }
}

void main() {
     Thread derived = new DerivedThread();
     derived.start();
}

Note that if you set "Thread.isDaemon = true" then you will need to 
join() the thread to wait for it to complete before the app exits.
