+- Engine/Pool:
+ - some new Pool utility classes, updated docs
+ - "use_threadlocal" on Pool defaults to False (same as create_engine)
+ - fixed direct execution of Compiled objects
+ - create_engine() reworked to be strict about incoming **kwargs. all keyword
+arguments must be consumed by one of the dialect, connection pool, and engine
+constructors, else a TypeError is thrown which describes the full set of
+invalid kwargs in relation to the selected dialect/pool/engine configuration.
+- Databases/Types:
+ - MySQL catches exception on "describe" and reports as NoSuchTableError
+ - further fixes to sqlite booleans, weren't working as defaults
+ - fix to postgres sequence quoting when using schemas
+- ORM:
+ - the "delete" cascade will load in all child objects, if they were not
loaded already. this can be turned off (i.e. the old behavior) by setting
passive_deletes=True on a relation().

-- fixed bug where eagerload() (nor lazyload()) option didn't properly
+ - adjustments to reworked eager query generation to not fail on circular
+eager-loaded relationships (like backrefs)
+ - fixed bug where eagerload() (nor lazyload()) option didn't properly
instruct the Query whether or not to use "nesting" when producing a
LIMIT query.

+ - fixed bug in circular dependency sorting at flush time; if object A
contained a cyclical many-to-one relationship to object B, and object B
was just attached to object A, *but* object B itself wasnt changed,
the many-to-one synchronize of B's primary key attribute to A's foreign key
attribute wouldnt occur. [ticket:360]

that the class of object attached to a parent object is appropriate
(i.e. if A.items stores B objects, raise an error if a C is appended to A.items)

the instance is an "orphan" only if its not attached to *any* of those parents
