A process shall be created with a single thread. If a multi-threaded process calls fork(), the new process shall contain a replica of the calling thread and its entire address space, possibly including the states of mutexes and other resources. Consequently, to avoid errors, the child process...

If you're working with a multi-threaded app that uses native thread APIs (such as the Win32CreateThreadfunction rather than the Python threading APIs), it's presently necessary to include the following source code at the top of whichever file you want to debug: ...

If the encoding argument was omitted when opening the file to write, the locale default encoding would be used, and we’d read the file correctly using the same encoding. But then this script would generate files with different byte contents depending on the platform or even depending on ...
