I'm pretty sure this is fallout from the "offset" fixes.  The observed
randomness probably depends on whether `realloc` in `makemessage` has
moved the object or not.  I think I can force it to always crash by
forcing the reallocation to get new memory.

Someone who groks the internals should look at this, b/c I see
omsgCount = 0, but omessage != NULL and I don't have time to learn
what does that mean and how the conditions to call
`thread_fix_old_links` should be tweaked.
