You'd store it (or a pointer to it) in the statement object, returned
by cursor.prepare(). Given that prepare() is a cursor method, the
cursor can be made aware of each such object.

This is very close to what I proposed, except that my cursor.prepare()
returns the statement (which you provide through cursor.command).
This allows one to prepare more than one statement using one cursor.
