This patch has been successfully tested by QE. After configuring two
memory-backends with preallocation context objects, binded to two host
nodes; the result is QEMU being at least three times faster than
before.
# time /usr/libexec/qemu-kvm -M q35 -m 16G,maxmem=32G -numa
node,memdev=mem0,nodeid=0

Allow the initialization to occur
QEMU initializes preallocated backend memory as the objects are parsed from
the command line. This is not optimal in some cases (e.g. memory spanning
multiple NUMA nodes) because the memory objects are initialized in series.
Allow the initialization to occur in parallel (asynchronously). In order
