This breaks "-icount auto" on qemu-system-aarch64 with "-M virt" and AAVMF firmware, in two ways: 1) "-icount auto" doesn't work; 2) "-icount auto -accel tcg,thread=single" hangs fairly early, printing this on the serial console. It's okay if it hangs at [Bds]=============End Load Options Dumping============= [Bds]BdsWait ...Zzzzzzzzzzzz... [Bds]BdsWait(3)..Zzzz... (pressing Enter a few times then seems to unhang it), but it now hangs much earlier than that. Also, x86 "-accel tcg,thread=multi" prints the scary message on memory ordering.
