Why do you need RAM_SAVE_FLAG_MULTIFD_PAGE?  I understand the
orchestration of sent pages from a single thread, but could the receive
threads proceed independently, each reading its own socket?  They do not
even need to tell the central thread "I'm done" (they can do so just by
exiting, and the central thread does qemu_thread_join when it sees the
marker for end of live data).
