Dear DragonFlyBSD bugs,

Alex Hornung recently (today ?) added mmap randomisation (security feature),
but in his commit he uses:

karc4random()

When he should really be using the superior kernel random number generator
presented to userland via

/dev/random

and

/dev/urandom

There are other portions of Kernel code which needs to do the same, e.g. I
think OpenBSDs PF Packet
Filter uses karc4random() ....
