Hehe, so the new flag is in a word we've already written to on this path
and it avoids growing the structure (by an undefined number of bytes,
see gripes about sizeof(bool)).

I am thinking of doing the thing you did for a debug aid -- then again;
if the Google guys would finally get the global vruntime patches sorted,
we can go and kill all this code.
