According to Wikipedia http://en.wikipedia.org/wiki/Latency_%28engineering%29#Packet-switched_networks latency means "the time from the source sending a packet to the destination receiving it". Therefore, latency is unrelated to whether the operation is asynchronous or synchronous. And also unrelated to whether it's one-way or round-trip. Latency exists for asynchronous and one-way transfer, because for current DBus implementations we need at least one context switch to transfer each message from the sender process to the receiver process. Emphasizing D-Bus is low-latency could encourage user to abuse/misuse the system.
