Yes; we've discussed this before in this thread: http://lists.nongnu.org/archive/html/qemu-devel/2011-08/msg01623.html That commit breaks multi-threaded usermode programs (well, even more than they usually are). I think we decided that the right fix was to make cpu_single_env thread-local (but that needs a slight change for windows, see one of the messages in the thread). -- PMM
