We may have many windows open, which tries to update/change the xcursor at various points. Track which cursor is currently loaded, regardless of which window it was set by. If someone tries to load that very same xcursor again, simply skip it. One example is when we've moused over a window that does *not* have keyboard focus, and then the user clicks, or by some other mean gives that window keyboard focus. In many cases it will then try to set the same cursor again (most of the times, the cursor is the same regardless of keyboard focus, but not always).
