Mapping Win32 thread priority levels to Linux nice levels is fairly 
trivial, but convincing kernel developers to allow unprivileged 
user-space programs to control thread priorities is the big problem. The 
last time a discussion like this came up, we (Wine developers and Cedega 
developers) requested a way of changing a thread's relative priority 
within a process (without affecting the overall CPU time the process 
gets). This should be a good compromise between meeting applications' 
needs and preventing unprivileged applications from freezing the 
computer. AFAIK, this hasn't been implemented yet.
