Hi,
	I=92ve been trying to figure out (because sysctl(9) is lacking) =
when to use CTLFLAG_MPSAFE. Is it strictly when dealing with SYSCTL_PROC =
handlers that do proper locking of shared resources, or are there other =
nuances that need to be handled?
	I=92m also asking because SYSCTL_UQUAD, for instance, explicitly =
uses CTLFLAG_MPSAFE in the handler, which is a bit confusing.
Thanks!
