Handle promises in transactions

[slorber]

When a promise resolve, all the stores registering listeners to it should be updated atomically.

Can it be done with Q?

[wmertens]

Q calls all promise handlers in a single blocking iteration. However, if those handlers in turn return resolved promises they will be handled on the next tick.

thanks @wmertens I didn't thought it was working this way.

So calling 2 times .then on a promise and the 2 then callbacks are executed in the same iteration? this is nice for me

[wmertens]

Yes, here's the function:

Basically all actions are put on a stack and on a tick the stack gets
cleared. New promises are asynchronous as per spec.
