The problem is that Wine uses XCloseDisplay to destroy all X windows 
created in that thread, but there is no equivalent functionality for 
GLX. If gdi_display = windata->display, it would remove the need for 
XSync, but the problem of zombie GLX windows would remain. I hope I 
understood your question correctly.
