stack. For that purpose, the ``Connection`` class keeps an internal
counter that represents the nesting level and is
increased/decreased as ``beginTransaction()``, ``commit()`` and
``rollBack()`` are invoked. ``beginTransaction()`` increases the

nesting level whilst
``commit()`` and ``rollBack()`` decrease the nesting level. The nesting level starts at 0. Whenever the nesting level transitions from 0 to 1, ``beginTransaction()`` is invoked on the underlying driver connection and whenever the nesting level transitions from 1 to 0, ``commit()`` or ``rollBack()`` is invoked on the underlying driver, depending on whether the transition was caused by ``Connection#commit()`` or ``Connection#rollBack()``.

What this means is that transaction control is basically passed to
code higher up in the call stack and the inner transaction block is
