Thanks. Indeed, seems to me the right way to go: a small, self contained 
example that people can easily review. I will actually look into it in 
detail over the next days.

A quick comment: can you possibly also add a simple performance 
testcase? I'm sure it's relatively easy to prepare an impressive one, in 
this area ;)

Thanks,
Paolo.
