It is a simple verb. According to Barak you already have such verb, but even if 
not then it can be added. Even post feature freeze, in stabilization cycle.

It is required. You can't put anything you need in stats and never to poll.... 
in addition ,we have added the infrastructure for a-sync execution, so it won't 
be blocked.

We discussed it and decided that my proposal the way to go, so either do it 
now, or in the future, but according to our agreements this is the way to go.
