The thread is never called. Any ideas? Thanks!

PS In an old DLL it used to work, there I called it with only one 
argument, i.e. spawn(&myFunction). Is thisTid messing it up, do I 
need to pass something else?

Mystery solved. There was an audio delay so that the program had 
already finished, before the thread was properly executed. I

That can happen on Linux as well. So, the owner may have to call 
thread_joinAll() to wait for the worker:

import core.thread;

     auto myThread = spawn(&myFunction, thisTid);
     send(myThread, arg);

     // ... sometime before the program ends:
     thread_joinAll();

Alternatively, one should use non-daemon threads for this purpose.

Yeah, I've read about that, I think Adam mentions this in his 
cookbook as well. For my application the thread merely plays an 
audio file and is interrupted as soon as new input comes. The 
issue only came up, because in a test program the app finished, 
before Windows started to play (audio delay). In the real world 
app this isn't a problem cause it stays up an running. But still, 
I'm experiencing some weird behavior that might be down to the 
whole threading thing. Happy debugging!
