That hasn't anything to do with finalizers. In advanced systems, that sort 
of stuff isn't something you write in the application code, either, any more 
than worrying about taking things out of the B-tree is something a SQL 
programmer worries about when deleting a row.

And yes, at IBM, when they were working in NIL (the precursor to Hermes), 
they ported a large and complex system from a single machine implementation 
to run on a distributed hot-failover cluster changing nothing but the 
compiler, just like you could with SQL code.
