In drama, movies, tv, and graphic storytelling, breaking the 4th wall is when the character turns to the camera/reader and directly addresses the audience, like in Scrubs. I've never actually heard of "breaking the 4th wall" applied to literature.
The narrative technique that Erikson has used here is technically called a "frame story." Famous frame stories include Canterbury Tales, in which the "frame" is a group of people on a pilgrimage, telling the "stories" to pass the time; Arabian Nights, in which the frame is Scheherazade telling the sultan stories to save her life; & Heart of Darkness, in which the frame is a sailor telling his story to while away a foggy night. In this case, the frame is the meeting of Kruppe, K'rul, and Fisher, followed by Kruppe's narration of the story, although it didn't seem to me that he was narrating either the events inside Dragnipur, or the saemankelyk arcs.
What I love about Kruppe telling this frame story is the plausible use of 3rd person omniscient because of Kruppe's mastery of Mockra. Usually it is implausible to use anything but 1st person to tell a frame story. WTG fantasy as a way to push the limits of literary craft!
