...this is after about 5 seconds. This thread just never gets quiet
and is
constantly churning. My system is idle too with nothing being added or
deleted or read from the database.

Those are the 2 noisy threads.
Ah, that does fit with what I see here, then. I took your "that just
never stop" to mean you were seeing significant CPU usage.
It's not good, certainly, but I guess it's designed on the assumption
that you're using it, ... so doesn't make quite the extraordinary
effort to avoid these wakeups that it otherwise might. I presume that
the timeout could be increased greatly when there's no activity to
monitor; but I have no knowledge at all of the mysql code, so I won't
claim it would be easy :o)
