The `@critical_section` directive instructs Argument Clinic to generate calls to `Py_BEGIN_CRITICAL_SECTION()` and `Py_END_CRITICAL_SECTION()` around the bound function. In `--disable-gil` builds, these calls will lock and unlock the `self` object. They are no-ops in the default build. This is used in one place (`_io._Buffered.close`) as a demonstration. Subsequent PRs will use it more widely in the `_io.Buffered` bindings.

Thanks! Can you please add tests? Also, we need to update the docs over at the devguide. Can you prepare a PR for that? |

This LGTM, sorry for the slow response! I'm not sure I fully understand what the @critical_section does, but that's more of a documentation question -- this PR looks fine. I'll try to find some time today or tomorrow to comment on the devguide PR you've put up :)
