Comment 1 for bug 1818075

<pm215> my guess is we're doing something unhelpful with the AVX insn, and so the guest code which is checking the result and using it as its loop condition for the jns is just looping forever

<rburton> in_asm log just stopped with this as the last line
<rburton> 0x4000b4ef4a: 79 9e jns 0x4000b4eeea
