--- Comment #12 from Bjoern A. Zeeb <bz at FreeBSD.org> ---
Making these variables per-VNET is not necessarily a good idea;  it means a
VNET-jail consumer could possibly DoS the system without the administrator
having a chance to prevent this easily by exceeding resources.

Need to be very careful.  I'd hope if this should go into HEAD that there'll be
a way to "cap" the values or reject excessive requests by some metric at least.
