Hello again Michael,
It doesn't look like libkqueue is linked to my emacs executable to me.

I ran the code you gave there, and did multiple writes to the file. The
following is the only text that appeared in *trace-output* and I believe
it appeared when I activated auto-revert, not when I wrote to the file.
======================================================================
1 -> (file-notify-add-watch "/Users/ccarpenter/test.txt" (change
attribute-chan\
ge) auto-revert-notify-handler)
| 2 -> (file-notify--descriptor 1080241180 "test.txt")
| 2 <- file-notify--descriptor: 1080241180
1 <- file-notify-add-watch: 1080241180
>From my amateur view it looks like we are not getting any notifications.
Does that help any?
