Extraneous error output when process exits after using subinterpreters #135729
Description
Bug report
Bug description:
I opened an issue earlier on the repo for the PyPI backport, but now that PEP 734 is implemented (🎉!) I am doing so here.
Reproducer:
>>> from concurrent import interpreters
>>> interp1 = interpreters.create()
>>> interp1.close() # same output occurs without this
>>> exit
Exception ignored while calling deallocator <function Interpreter.__del__ at 0x7308402c8460>:
