QEMU initializes preallocated backend memory as the objects are parsed from

multiple NUMA nodes) because the memory objects are initialized in series.
Allow the initialization to occur in parallel (asynchronously). In order to
ensure optimal thread placement, asynchronous initialization requires prealloc
context threads to be in use.

So, this LGTM. There might be ways to not rely on phases to achieve what
we want to achieve (e.g., let the machine set an internal property on
memory backends we create from the cmdline), but this should do as well.
I'll wait a bit for more feedback. If there is none, I'll route this
through my tree (after doing a quick sanity test).
Thanks!
