I'm on FreeBSD, I followed John Wong's suggestion, and did
--with-notify=pool   - which I think was a typo equivalent to 'none',
but I have no file notification method now.  Where before it was kqueue.
This seems to work fine for me.

So unless I missed some posts, maybe the question is:  How did the file
notification get to be kqueue, when my I/O loop was poll, and the
defaults for notify are either dnotify or none?
