When I analyzed 8kun about 5 or so years ago, I noticed it was almost all mainly PhP and JavaScript code.
1. Php is single threaded
2. The JavaScript I saw, did not use any techniques to mimic, multi-threading.

This is why I say, the image server is probably in-process because the language and techniques supporting them are. And if I remember correctly, the image server is based on WebDav, which most implementations were not written to be multi-threaded because they were just based upon Java's first iteration of the File objects, which were basic IO that didn't even have any interfaces, so that means if something was ever written that way with no interfaces, then you cannot switch out the implementations to the newer Networked IO called NIO without rewriting every line.
