Ruby odbc statement releasing

class MyDatabse < ODBC::Database
  def initialize()
    super
    @driver=ODBC::Driver.new
    @driver.attrs['dsn']='my_dsn'
    self.drvconnect(@driver)
  end
  def get_table(tablename)
    self.run("SELECT * FROM #{tablename}")
  end
  def finalize()
    self.drop_all
  end
end

myDB=MyDatabase.new
table=myDB.get_table('some_table')

···

-----------------------------------------------

the self.drop_all should be dropping all open statements when myDB is
garbage collected. For some reason, I'm still getting a 'WARNING:
statement XXXXXXX was not dropped before garbage collection.'

Does anyone know why this is happening?
