I just reinstalled my GNU/kFreeBSD system and I tested it outside a
jail, and ktrace tells me it does not access /dev/mem anymore.

I've also fixed an issue when kvm_getprocs(3) does not find any pid,
which might have also been involved in the errors you where seeing.

Something else I just realized now is that libkvm pulls in libbsd and
libfreebsd-glue into the pseudo-essential set on GNU/kFreeBSD, which
makes the situation a bit worse. So as stated above I'll be switching
to sysctl(2) later on, but I'm open to a revert if this is deemed
problematic too. Thanks for input Steven!
