How can I capture network traffic of a single process?

I would like to examine the network traffic being handled by a single process, but simple network captures won't work since I am dealing with such a busy system (lots of other traffic happening at the same time). Is there a way to isolate a tcpdump or wireshark capture to the networking traffic of a single specific process? (Using netstat is insufficient.)
