> If you're relying on Python garbage collection to free file descriptors in a loop
Again, that's a proscription for how to write python code for future execution. It's emphatically not a statement for the behavior expected by python code already in production, which tends to rely on this behavior (along with many other such warts and subtleties) implicitly.
And the fact that PyPy doesn't feel the need to clone it (and all the others) explains why PyPy basically doesn't work for existing python code.
I mean, me being an idiot python developer in your eyes does nothing to make the ancient code I received run. It just makes you feel smarter. That's a bad trade.
PyPy needs to be compatible before anyone is going to use it. And it isn't. And so people didn't. And so now it's basically dying as no one wants to work on a project no one uses.
It's not about feeling smart or dumb. I'm not doubting that lack of perfect compatibility is holding pypy back, though I suspect it's more related to C extensions and libraries than it is to bug-for-bug compatibility with the garbage collector. I just think that code which does this specific wrong thing that you've mentioned is already doomed to not work reliably even under CPython.
