The only documented use of subinterpreters is in mod_wsgi and Java Embedded Python (JEP). This is possibly due to their hidden nature. Though multiple interpreters have been available since the early days of Python, and they provide a number of features comparable to multithreading and multiprocessing, they simply aren't commonly used. To be honest, this author wasn't aware of them until finding this PEP, but they sound very useful for certain parallel-processing projects.
