Resource Timing "startTime"

"The|startTime|attribute must return the time immediately before the 
user agent starts to queue the resource for fetching"

I think it would help clarify the spec if the queue was defined a little 
clearer.  In the case where there is a long queue of resources to be 
fetched from a given fqdn (say, 100 images and 6 parallel connections 
per fqdn), is this the point at which it enters the backlog queue or is 
this the point at which it exits the backlog and gets scheduled on an 
actual socket?

If it is the point at which it enters the backlog queue can we add a 
block at the front of the diagram that includes the "blocked" time?  If 
it is the time when it gets scheduled on a connection can we indicate 
that it will always equal either the redirectStart or fetchStart time?

Thanks,
