In a subinterpreter, spawning a daemon thread now raises an exception. Daemon threads were never supported in subinterpreters. Previously, the subinterpreter finalization crashed with a Pyton fatal error if a daemon thread was still running. * Add _thread._is_main_interpreter() * threading.Thread.start() now raises RuntimeError if the thread is a daemon thread and the method is called from a subinterpreter. * The _thread module now uses Argument Clinic the new function. * Use textwrap.dedent() in test_threading.SubinterpThreadingTests

Oops. Typo in my PR title: "bpo-37266: Daemon threads are now denied in subinterpreters". |

I chose to add the new function the _thread module to not add a dependency (import) between thread and . For example, I would prefer that threading doesn't import _xxsubintepreters. The module is private, its API is a work-in-progress and it may pull other things which are not needed by threads. |
* use print() using flush=True * make the read end of the pipe non-blocking to avoid hanging forever
