--- Comment #21 from mcdouga9 at egr.msu.edu ---
I have been using this patch for a while on two desktops (4G and 16G) and my
swapping activity has stopped with no visible negative impact.  Positive impact
for me is no longer having to wait for applications to swap back in when I need
to use them.  I tried r265945 and vm.lowmem_period=0 and neither were as
effective as the patch in this bug report.  I plan to roll this patch into my
next build for general deployment to my servers and start experimenting with
removing my vfs.zfs.arc_max setting which I am currently using on some.  I hope
it can gain enough consensus to at least commit to -current.  Thanks.
