qemu+kqemu: hard lockup with windows guest (32-bit on 64-bit)

[Andriy Gapon]

System:
stable/7 amd64 r190321
qemu-0.10.0_1
kqemu-kmod-devel-1.4.0.p1_1

I experience rare complete system lockups while running windows (98, win2k) guests
with kqemu enabled. The guests are obviously 32-bit.
I can't provide any diagnostics because it's a total freeze and there is no useful
info after rebooting.
