           Summary: test case demonstrating PeekMessage give up timeslices
           Product: Wine
           Version: 20050725
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED

          Priority: P2

Hi,  
  
the test case whitch demonstates the differece between Windows   
and wine.  
  
On Windows XP  
- Start 'test.exe' from a dos-box... you see some FAST counting integers  
- Start a other program witch consumes mutch cpu time.  
- the output of 'test.exe' is slower but FAST  
  
On wine  
- Start 'test.exe' from a dos-box... you see some FAST counting integers  
- Start a other program witch consumes mutch cpu time.  
- the output of 'test.exe' is very slow  
  
This different behavior starts from wine version 20041201. The version before   
was ok.  
  
I have no patch and it would be nice if someone can write a patch to fix this.  
  
Thanks
