Alright, here it is. Now that I look at it, iterSelect() is indeed in
the backtrace, but the assignment is in _init, which means it's when
the object instance is created.
Thinking about it a little bit more, I realize that the problem might
actually be one that I fixed *after* stumbling on this, that some
objects were being leaked across threads due to a mutable class
attribute.
One way or another, the assignement here will add _connection to the
instance __dict__, where as the ConnectionHub is in the class. If they
are the same object that assignement could possibly be skipped, which
would end up avoiding the problem that I hit, which was that since
_connection was in the instance, it was the same across all threads.
In summary, it's not that big of an issue as long as you don't
(intentionally or unintentionally) share your SQLObject instances
across different threads.
