kern/146528: [zfs] Severe memory leak in ZFS on i386

[Michel Le Cocq]

ok in fact I didn't understand your first question !

I see this trouble only on my personnal i386 machine.
I have also several amd64 with a lot of mem 24G or some virtual with
4G all on amd64 and they work perfectly on 8.2 since more than 1 year.
