ZFS arc sizing (maybe related to kern/145229)

[Peter Schuller]

For the record I found this:

   http://svn.freebsd.org/viewvc/base/head/sys/cddl/contrib/opensolaris/uts/common/fs/zfs/arc.c?r1=197816&r2=197815&pathrev=197816

Presumably this should prevent the ARC going below the asked-for
minimum, though it doesn't fix the fundamental balancing issue between
ZFS ARC and the rest of the system.
