Sometimes, it is desirable to ``uninitialize'' Python. For instance,
the application may want to start over (make another call to
\cfunction{Py_Initialize()}) or the application is simply done with its
-use of Python and wants to free all memory allocated by Python. This
+use of Python and wants to free memory allocated by Python. This
can be accomplished by calling \cfunction{Py_Finalize()}. The function
\cfunction{Py_IsInitialized()}\ttindex{Py_IsInitialized()} returns
true if Python is currently in the initialized state. More
information about these functions is given in a later chapter.
+Notice that \cfunction{Py_Finalize} does \emph{not} free all memory
+allocated by the Python interpreter, e.g. memory allocated by extension
+modules currently cannot be released.
