A question about code

[Mountas-Liu]

Hello, I have a question about code in abstractmem.cc .
if(senderState->isRegistration()){ pendingPIMqueue.push_back(senderState); pkt->popLabel(); delete pkt; }
When abstractmem receives a request package, it will push it into pendingPIMqueue. However, I didn't find the place where the PIM device handles the requests in this queue. Can you give me some advice? Thank you very much.
