This looks really cool. The "only" complication on x86 is the large
number of compile and runtime options that we have. When this gets
merged, it would be really nice to make sure that the 0day guys have
good coverage of all the configurations.
I'm not _quite_ sure what kind of bugs it will catch on x86 and I
suspect it'll have more value for the other architectures, but it seems
harmless enough.
