> I was a bit brutal in the first review -- we kind of live in a world
right now where our RPC code can just let stuff run for a very long time (you
inherited a bit of the problem).
There were so many things to consider for this feature. I am really glad
you made me focus on this aspect.

The session concept that some of the code currently uses (like scans)
defends against the following :
* Doing work for a client that is no longer there.
* Clients starting a second instance of a task, while the first is still
processing.
The current code is susceptible to both of the problems above and I would
like to avoid that.
