- * https://pybind11.readthedocs.io/en/stable/advanced/misc.html#global-interpreter-lock-gil

- * The pybind11 versions are however too sophisticated (using TLS for example) and don't work well with all kinds of

- * See also https://github.com/pybind/pybind11/issues/1276, which may be related.

- * Briefly, GilScopedAcquire can be used on actor creation to acquire a new PyThreadState. The PyThreadState has to be
- * released for context switches (i.e. before simcalls). That's the purpose of GilScopedRelease.
- *
- * Like their pybind11 counterparts, both classes use a RAII pattern.
