--- Comment #8 from Mark Johnston <markj@FreeBSD.org> ---
Using truss on the host I can see that we are mprotecting the last page

It doesn't show up in qemu's strace output, so presumably this is something
internal to qemu.  The only syscall which looks relevant here is a
sysarch(ARM_SYNC_ICACHE), but it looks like qemu treats that as a no-op...
