Isn't the fact that the former updates the MSI message data without
updating the copy of it in memory a problem for the latter, i.e. won't
the latter restore stale information? While the problem (if there is one)
existed before c/s 20073, the fact that the vector now can change
seems to make the potential effect of this much worse.

Thanks, Jan
