Pétur, I had the VERY SAME thought!

In particular, about your first point, the reason why I didn't post
something is that I was unsure about the Boost license, I understand
from your message that is already GPL... Great!

About your second point, I spent a few days about one week comparing
our SGI/HP code to Matt proposal. Indeed, the differences seem not so
big, will post something soon. The most important being the (controversial!)
"bucket interface" and the missing maximum load factor control.

Paolo.
