This only solves one point (but is needed nevertheless).

As I've showed in the last message to Alexander yesterday evening you 
need to initialize some things PER THREAD and I don't know whether this 
can be automised. We might need to ask the FPC devs for help regarding 
this. Perhaps the first time a threadvar in this new thread is accessed 
might be a good possibilty, but I don't know (yet) how we could track 
whether this is the first call, because threadvars are not yet allocated 
(hen-egg-problem). I'll have to take a deeper look into the threading 
system on Win32 :)
