[Zope] Progress information for long running process

[Oliver Bleutgen]

Other alternatives, if you don't have the email of the user and showing 
logs is not important, are
- A javascript which visibly counts down 30 minutes and the goes to take 
the result
- Return a specific link to the user where he can check himself if 
there's a result
- Offer the user to set the above URI as a bookmark (maybe with javascript).
- Set a cookie so that you can remind the user that "there's something 
waiting for you, click _here_" on adequate pages of the site (front 
page, user homepage, whatever)
- any combination of the above

It's all a question of how many resources one is willing/able to spend, 
I'd prefer to avoid involving zope too much just to show the user some 
ascii animations for 30 minutes.


cheers,
