Supposedly the most important tuning parameter of course is the count of 
usable CPUs, the next important being the predicted percentage of the 
effort to start a thread regarding the runtime the thread needs to 
complete. For "lightweight threads" (requesting for a thread pool at 
least in Windows) this percentage might be rather low, for normal 
Threads somewhat larger. IMHO we should consider PC arrays as well. Here 
this percentage of course is a lot larger (transferring parameters and 
results through a Network), but here we might have a huge number of

Too humble, IMHO, changes to the language should be very well considered. :)
