Re: kern/55663: Support for EVFILT_USER in kqueue(2)

Sorry, I did not have time to write a summary yet. Hopefully, I will get 
more time this week and will give some update.

I guess, the larger point was that some applications (e.g., nginx and 
others) already use this feature because FreeBSD implements it. 
Otherwise, they would compile a much more restricted version -- that was 
the reason why it could be really beneficial.
