Hi,

I saw this free lists implementation this morning in the floatobject and 
listobject sources,

which already handles the reuse of objects. I must admit I like this 
implementation. It's pretty smart.

And yes I'm a little bit disappointed because it reduces the benefit of 
my idea a lot.

Regards,
Martin
