It has been pointed out that SA depends on __del__ to clean up its

be totally explicit and customizable to allow applications to scale in
varying environments. Application developers need to be able to
control when and how resources are obtained and released. Finally,
resource management is orthogonal to the real job of SA, which is to
map database data to objects.
while you may not have noticed there is a critical ticket to add
explicit reference counting to the connection pool and to build this
functionality in by default, you are free to provide your own Pool class
to the SQLEngine and connections can be managed in any way you like.
Sorry. I need to pay more attention to Trac.
