gives me an empty spidx.diff, patched spatial index is identical to 
original spatial index

Waiting for Glynn's comment, then I would commit.

Now that we are warmed up, we could tackle the dglib cache problem and 
enjoy avl trees, sorted heaps, Dijkstra search and other goodies hidden 
in dglib, what do you think Glynn? :-)

Maybe I need a little break...

But a first wild guess for BUG1 in [1] is that point 3 is skipped when 
it was visited before. In dglib, a point gets flagged as visited, 
clearing this flag before doing a new search could help (here comes the 
first avl tree).

I need a break indeed.
