[New-bugs-announce] [issue34651] Disallow fork in a subinterpreter.

[Eric Snow]

New submission from Eric Snow <ericsnowcurrently at gmail.com>:

os.fork() potentially has some problematic behavior when called from a subinterpreter.  In additional to the normal fork+threads madness, there's the question of what to do with existing subinterpreters.  The simplest solution is to simply disallow fork in a subinterpreter and then wipe out all subinterpreters in the child process post-fork (if os.fork() called in the main interpreter).
