+Subject: [PATCH] sdl.c: allow user to disable pointer grabs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When the pointer enters the Qemu window it calls SDL_WM_GrabInput, which calls
+XGrabPointer in a busyloop until it returns GrabSuccess. However if there's already
+a pointer grab (screen is locked, a menu is open) then qemu will hang until the
+grab can be taken.  In the specific case of a headless X server on an autobuilder, once
+the screensaver has kicked in any qemu instance that appears underneath the
+pointer will hang.
+
+I'm not entirely sure why pointer grabs are required (the documentation
+explicitly says it doesn't do grabs when using a tablet, which we are) so wrap
+them in a conditional that can be set by the autobuilder environment, preserving
+the current grabbing behaviour for everyone else.
+
