Miss Islington (bot) eed3c7af4e bpo-32604: Swap threads only if the interpreter is different. (gh-5783) 
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.
(cherry picked from commit f53d9f2778)

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.
