the point is that we currently don't trace pure unix process as being 
windows processes
hence you lack the ability to get some information on them (wait on 
exit, get return code...)
one of the things we could do is to:
1/ create a winelib app (say winixec) which does basically:
        WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR 
lpCmdLine, int nShowCmd)
            return system(lpCmdLine);
2/ setup the application to be called as "winixec  foo args" instead of 
"foo args"

this would work in some of the cases, but fail for all the other 
operations (resume/suspend, debug...) which shouldn't be an issue in 
your case
