It'd be helpful to find a version of SO that doesn't freeze.
Unfortunately it requires to rollback your code and to run a lot of
experiments.

There shouldn't be any path -- you use sqlhub as the connection:
class MyClass(SQLObject):
_connection = sqlhub # Actually, this is the default
sqlhub.threadConnection = connectionFromURI('...')
Sqlhub's __get__ and __set__ methods return the real connection.

You can see the code at dbconnection.py stared at the line 332: class
DBAPI, method getConnection. You can explicitly disable the pool by
setting dbConnection._pool = None.

Should be. The pool is protected by _poolLock. Does something in the
code trigger your suspicions?
