That's not particularly great as the swcursor has several issues. Apart from the (presumably expected) flicker, the cursor also tends to leave horrible trails behind around dri2/3 windows (happens with tearfree at least). To avoid some of that let's try to switch back to the hwcursor a bit sooner. We can do that neatly via the convenient swcursor block handler. v2 [ickle]: Apply the restoration after the screen update is complete. v3 [vsyrjala]: Push it back to restore_swcursor and remove the fullscreen redraw -- prevents terrible flickering in v2!
