I'm pretty hard pressed to explain this from the set of commits
currently under test, but it has happened a few times now (e.g. 56700
56576) so it does seem to be real.

http://logs.test-lab.xenproject.org/osstest/results/bisect.xen-unstable.test-armhf-armhf-xl-multivcpu.leak-check--check.html
is working on it and is currently consider the set of changes from:
ianc@cosworth:xen.git$ git log --oneline 9ab42~1...45fcc4
45fcc45 use ticket locks for spin locks
e13013d libxc/restore: add checkpointed flag to the restore context
ce44b40 libxc/restore: introduce setup() and cleanup() on restore
c5c5a04 libxc/restore: split read/handle qemu info
9ab42c9 libxc/restore: introduce process_record()

where e13013d is current master which was pushed in by flight 56375.

I think it unlikely the libxl stuff is responible, given we don't
migrate on ARM, which would seem to point to the ticket locks...

Ian.
