I figured it was something like that, but it didn't say anywhere. Can
I create sets myself, btw?

I'm trying to use the ZODB to store and index large quantities of XML
data. I'm especially interested in fast retrieval of data and I need
some form of join algorithms. Here I figure the BTree module intersection etc
operators can come in handy -- are they supposed to be fast?

What happens if I keep a BTree in-memory anyway? I mean, if I just
create a BTree as a local variable, does the entire structure exist
in memory then? And how efficient is this? :)

There's Interfaces.py, but that's all I could find so far.

Thanks,
