--- Comment #4 from Dan Kegel dank@kegel.com 2010-08-27 08:57:32 --- It's not especially good that we need a suppression file for memcheck for wine either, but you have to start somewhere.
Somebody needs to start sweeping with the data-race detector and clean up all the errors just like we did with memcheck. (We're still not done with memcheck - we never cleaned up wineboot.) It's a big job, but maybe a few days would help a lot.
