This is not going to answer your question, I just state the obvious:
why don't you use the debugger, set a breakpoint in some suitable
place, and see the stack trace to understand the program flow?

Debugger breakpoints and stack traces are much more powerful than just
some random printouts. Check out http://trac.webkit.org/wiki/CodePaths
for some inspiration.
