Yeah.. sorry if I wasn't specific in my comment, referring to DomU and
not VMX domain. But the comment remains.

This patch does not completely fix the race in qemu-dm for VMX domains.
I tested this patch on my SMP system and the corruption still happens. I
couldn't successfully transfer a 2 gb file from Dom0 to a VMX domain.
The VMX domain is still seeing corruption.
