I'm seeing an infinite loop in xfrd on the destination physical machine,
when migrating a domain.  It passes 100% while reloading memory pages,
and keeps going.  I've seen this on an older build (an early 2.0.x IIRC)
but have never yet had time to dig into it.  Anyone else seen this?

Here's /var/log/xfrd.log:
