It gave problems for some users nevertheless. And I already posted a 
patch that does something like this once, but nobody cared to make it an 
option.
I'm also not sure if THREAD_PRIORITY_TIME_CRITICAL exists on e.g. win98 
can someone check? And last but not least I'm not too sure if raising 
thread priority will help enough - I might test if I ever boot into 
Windows again ;-)
