Changes for the BitKeeper resolve.

One more notice:

limiting number of queries per hour for different users has been done
on 4.0.1 , but I can port it to 3.23.* 

This will require only certain changes, like number of columns in user
table.

I will also make a test case for it, after it is approved by Monty, 
as result file will depend on the error message text.
