@alexmalyshev: There are now merge conflicts, can you try to solve them? Moreover, a new max_threads parameter has been added. Can you update your PR to add it? |

There is no tests on the newly added C APIs. These functions are tested indirectly by test_faulthandler. |

These functions stopped being exported in #107215. However, they are the only way to print a Python stacktrace safely from a signal handler, making them very useful for extensions. Re-export them.
Regenerated from #145560 due to a bad merge.
