bpo-34651: Only allow the main interpreter to fork. (gh-9279)
When os.fork() is called (on platforms that support it) all threads but the current one are destroyed in the child process. Consequently we must ensure that all but the associated interpreter are likewise destroyed. The main interpreter is critical for runtime operation, so we must ensure that fork only happens in the main interpreter.

bpo-33615: Re-enable subinterpreter tests. (#7552)
All the subinterpreter tests were disabled in gh-7513. This commit re-enables them, but leaves one bad test disabled. The test is partly causing problems because it makes assumptions about the availability of a high-level interpreters module (see PEP 554). So I'm disabling the test until such a high-level module is available.

bpo-33615: Skip test__xxsubinterpreters (GH-7503)
The test does crash on multiple CIs causing many troubles. For
example, the test prevents to get results of the two Refleak 3.x
buildbots.

bpo-33615: Re-enable a subinterpreter test. (gh-7251)
For bpo-32604 I added extra subinterpreter-related tests (see #6914), which caused a few buildbots to crash. This patch fixes the crash by ensuring that refcounts in channels are handled properly.

bpo-33615: Temporarily disable a test that is triggering crashes on a few buildbots. (gh-7288)
For bpo-32604 I added some subinterpreter-related tests (see #6914) that are causing crashes on a few buildbots. I'm working on fixing the crashes (see #7251).  This change temporarily disables the triggering test.

bpo-32604: Implement force-closing channels. (gh-6937)
This will make it easier to clean up channels (e.g. when used in tests).

bpo-32604: Improve subinterpreter tests. (#6914)
Add more tests for subinterpreters. This patch also fixes a few small defects in the channel implementation.

bpo-32604: Swap threads only if the interpreter is different. (gh-5778)
The CPython runtime assumes that there is a one-to-one relationship (for a given interpreter) between PyThreadState and OS threads. Sending and receiving on a channel in the same interpreter was causing crashes because of this (specifically due to a check in PyThreadState_Swap()). The solution is to not switch threads if the interpreter is the same.

bpo-32604: Expose the subinterpreters C-API in a "private" stdlib module. (gh-1748)
The module is primarily intended for internal use in the test suite.  Building the module under Windows will come in a follow-up PR.
