-----------------------------------------------------------
>>> latency = await + this task's processing time, right?
Currently it is just the processing time... what i am proposing is to change
the latency number to something like await (await in the queue + processing
time). If that makes sense.
>>> not sure why we'd remove the latency though
I am not saying we have to remove it... Just like a enhancement instead of
adding one more metric to glance :)
