Hi Valery,

In the future, please make your commit messages more explanatory. 
"Iterative scheduling infrastructure + minimal registry scheduler" tells 
me next to nothing about what this is or how it works. It is obviously 
an extensive addition/change. The review had a good summary, and that 
should have appeared here (updated to reflect any changes made as a 
result of the code review).

I'd appreciate it if you would reply to this thread with the updated 
summary.

Thanks,
Hal
