f53d9f2778 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.

c1e46e94de bpo-32777: Fix _Py_set_inheritable async-safety in subprocess (GH-5560) 
Fix a rare but potential pre-exec child process deadlock in subprocess on POSIX systems when marking file descriptors inheritable on exec in the child process.  This bug appears to have been introduced in 3.4 with the inheritable file descriptors support.

This also changes Python/fileutils.c `set_inheritable` to use the "slow" two `fcntl` syscall path instead of the "fast" single `ioctl` syscall path when asked to be async signal safe (by way of being asked not to raise exceptions).  `ioctl` is not a POSIX async-signal-safe approved function.

461d225b19 bpo-32674: Improve the docstring for __import__ (GH-5339) 
Clarify that the level argument is used to determine whether to
perform absolute or relative imports: 0 is absolute, while a positive number
is the number of parent directories to search relative to the current module.

The module is primarily intended for internal use in the test suite.  Building the module under Windows will come in a follow-up PR.

c65ef772c3 rename _imp initialization function to follow conventions (#5432) 
When the C imp module became _imp in 6f44d66bc4, the initialization function should have been renamed from PyInit_imp to PyInit__imp.
