I think I might want to try lifting the original limitation here, move the flush accounting inside the autocommit transaction .

Moved the post flush as well as the event hook into the try/except block in 8f381f202e569eda0d5de13f584304440492222c. The change to autoflush=False is that the accounting + the hook are inside the scope of where rollback() would be called. There's a potential for backwards incompatible here if people have post_flush_exec hooks that either throw exceptions or call rollback(). Let's see how it goes.
