Not sure what the issue is for the first aspect here, do you just need to
call Session.flush() ?

It's nice to see sqlalchemy provides a way to hold database locks.
This is a good option but my customer didn't like this since he
believes his system will be highly concurrent.

The statements that are executed as a single statement make no such
check (and the database engine correctly translates a string to
integer), but cursor.executemany checks type:

cursor.executemany(statement, parameters)
TypeError:
Oh. Makes sense. Then the only reason I'm starting to hit this is
that you've optimized the orm to use executemany() more often,
correct?

I have a relatively complex structure to my data. In essence it's something
like:
* A Foo is a small object containing some data.
* A Bar has a fixed number of (say, 3) references to Foos
* A Baz has a single Bar, plus one additional Foo
* A Qux has a single
In case anyone was going to attempt to solve this, I have come up with a better
way to approach the problem. The data is still structured the same way, but I
am now going to traverse it in a different way, such that I no longer need a
Foo to be aware of everywhere it is being referenced from.
