While trying to understand the extent of our spinlock usage, I noticed that
WaitEventCustomCounterData->mutex is unnecessary because the counter is
only ever accessed with WaitEventCustomLock held exclusively. So, here's a
patch to simplify matters a bit. Thoughts?

Indeed. This removal sounds good to me, thanks.

#include "storage/spin.h" seems no longer needed in wait_event.c,
since the patch removes the last use of the spinlock code there.
So we can remove that include as well?

I think so. I've committed the patch with that change. Thanks for
looking!
