Nice!

The following might be related: I'm seeing segfaults with -smp 8
and beyond when doing bootup+shutdown of an aarch64 guest on
an x86-64 host. smp -1 is stable AFAICT. The first commit that
shows these crashes is "tcg/i386: Use TCG_TARGET_NEED_LDST_OOL_LABELS",
that is f7ec49a51c8 in your tcg-tlb-x86 github branch.
Thanks,
Emilio
