The best help would be if we could write a simple test program that generated the problem. If we can see when it occurs, we can better understand why Dazuko is missing the CLOSE events (or why there are no CLOSE events).

With certain programs (such as Firefox), it is always the same files that are not seen as closed. I'm trying to find simple programs that cause the phenomenon because they will be easier to debug.

I don't think dup() helped clean up the problem, but dup2() probably did. With dup2() it is possible that CLOSE events occur (when you dup to a file descriptor that is already in use). There must be more of these type of system calls (that implicitely close files).
