Any guidelines that dictate this?

Oops, indeed it could be left un-initialised. My bad.

I presume that should be using KIDLETIME for the category?
Isn't it possible to get the `KIDLETIME()` symbol through libKF5KIdleTime rather than \
having to pull in `../../logging.cpp`?

As far as I can see all it can be used for is to print a warning, right?

Yeah, that seems logical, but I don't see any documentation on what setupPoller() \
should return. Then again the upstream code doesn't appear to use the return value \
anyway so the question is a bit moot ...

OK, but among the final things to do before committing :)

The bingo isn't mine!
Oh, the code. As above, in final cleanup :)

The original code worked rather differently. It used a mechanism with an internal \
poller, but you're right, the wording as it is makes sense only to someone who went \
about replacing that original code and made a number of (trial-and-)errors on the \
way.

I put the commented code as a reference for alternative approaches that could be \
investigated once more if ever `updateSystemActivity` is removed. If there's a policy \
against such comments I can also store the snippets in a separate file, but that \
means adding one. What's preferable?

That one actually got through and was never meant to!

I've learned to be fool-proof with this kind of thing (I don't trust `delete` to zero \
memory before releasing it; there's no `~CocoaEventFilter()`) but what does make it \
redundant here is setting `m_nativeGrabber = 0` just after deleting `nativeGrabber`.
