As decribed here:
There are 31 priority levels and only users with Administrator 
privileges can set processes to the highest priorities of 16-31.
I doubt there are programs that require these high priorities, although 
we could find potential targets by printing a message for programs that 
try and set their priority to a high level.

>>>and how wine treats that scheduling (which I also don't).
Wine performs local procedure calls to a server to perform the 
equivalent of Windows syscalls. It does this over Unix domain sockets. 
Processes block while waiting for data from the server.
