Hi Dave,

I see lots of $SUBJ generated by the current snapshot of trinity.
0x4120ae below is free in the loop in post_move_pages. So this is
perhaps introduced with one of:
commit ae3b98fcbf52c808b0a3eb4eb5311c9fdf433f55
Author: Dave Jones <davej@redhat.com>
Date:   Wed Jan 8 11:08:22 2014 -0500

    only allocate page_types array once

commit 2a749813619348b3bfd144fe04488f698d83accc
Author: Dave Jones <davej@redhat.com>
Date:   Tue Jan 7 12:11:11 2014 -0500

    teach move_pages about the maps list


Any ideas?
