The GC may collect it as soon as there's no reference to the 
Thread object anymore. But you'll probably want to keep a 
reference anyway, to join it (wait until it's finished), 
something like:

Thread loadFileAsync(string path)
{
   // start() returns `this`
   return new Thread({ writeln(readText(path)); }).start();
}

void main()
{
   auto thread = loadFileAsync("foo.txt");

   // [do something useful in parallel]

   // wait for other thread
   thread.join();
}
