I'm fine with splitting the patch up to make progress. I'll post a
split patch shortly.
Would you mind explaining what complexities you see for vectors? As per
my direct email, the set of vectors which can practically be made atomic
may be smaller than we'd like, but the existing atomic semantics seem to
map cleanly. What am I missing?
