@mm, I'm not entirely sure if this is the same thing, but there seems to be a "System Request Queue" (SRQ) which handles communication between cores. See here http://www.anandtech.com/show/1665/2.

EDIT: I think it's actually the "Global Queue". According to http://sc.tamu.edu/systems/eos/nehalem.pdf (pg 35), "The GQ bufers, schedules and manages the flow of data traffic through the uncore." More specifically, it queues and handles memory read/write requests from the 4 cores.
