(info "(org) session"):

,----
| The ‘:session’ header argument starts a (possibly named) session for an
| interpreted language where the interpreter’s state is preserved.  All
| code blocks sharing the same name are exectuted by the same interpreter
| process.  By default, a session is not started.

The interpreter that geiser runs is specified in
geiser-default-implementation.
