Actually no, I was asking how Rich would name the constants if we use
the name "file-description locks" (as per the patch I posted this
morning), since his objection was the use if *_FD_* names.

I would assume that if we stick with "file-private locks" as the name,
then we'll still change the constants to a form like *_FP_*.

Also, to be clear...Frank is correct that the name "file-private" came
from allowing the locks to be "private" to a particular open file
description. Though I agree that it's a crappy name at best...
