Excellent indeed.  And look how short the patch is!  The only things
that immediately come to my mind are:

  - Needs locking around the cache.  Then you can use a static cursor
too, for faster lookup (a cache of one there in itself).

  - With just backend comparison, does this work with two different X
displays?  Guess not.

  - We have a faster random() implementation in cairo.  Lets use that.
