Yes, it's all pretty confusing.  We have quite a few pokers in the fire
right now.

The thread support only allows the I/O to be concurrent.  Execution
inside your app will still be nonconcurrent until Zope2.

Beta, we should be so lucky! :^)  As Chris mentioned it's alpha, for the
reasons he stated.

As explained above, no, just to read input from the browser and send
output back to it.

Zope2 is the push for concurrency.  This involves two main areas: a
concurrent publisher and a concurrent transaction system.

The first area is ZServer, which as you can see is coming along nicely.
The second area is the "BoboPOS3" effort to make the database and the
transaction manager able to have multiple simultaneous requests.

We expected to get the database work caught up with ZServer this month,
but a customer project pushed Zope Classes up the priority scale.  If a
customer gig comes along the requires concurrency it will certainl
displace other things at the top of the list.

BTW, prepare to be dazzled by Zope Classes.  When combined with Zope
Property Sheets, it's going to radically change the way folks think
about data on the web.

I believe you are correct, sir.
