Sorry for murdering the language here, what I want is something that has
executional persistence.

My point is that it could be possible to preserve the stack, etc. by
going fuzzy on granularity.  Also, I have a tendency to think in terms of
the likely nuts of bolts of the thing; if it is coded throughout as
transactions, then there's the option of having a mode where there is
atomicity.

What is world-global synchronization and how does it occur?
Alternatively, how does one deal with disjointness in data?
