[Interest] Reasons why deleteLater() might not work

So buried deep in the code base (which was being reused from another project) was an event filter that was specifically looking for deleteLater() and then swallowing it up. I need to figure out why in the other project we were doing that. I knew it was "user error", just needed some help getting me point in the right direction to look for issues.
We would like to clean up children items when they are removed from the UI. They are generated on the fly and may contain heavier data that one would want just laying around. Now that deleteLater() is working, in fact we just remove the single parent, call deleteLater() on it and everything finally gets deleted as it should.
Thanks everybody for the help.

Also, I don't even remember a single case where I ever needed deleteLater().
