[New-bugs-announce] [issue33191] Refleak in posix_spawn

[Zachary Ware]

New submission from Zachary Ware <zachary.ware at gmail.com>:

There is a refleak in posix_spawn; see for example http://buildbot.python.org/all/#/builders/114/builds/53

The attached PR fixes it, but I am not confident that I did it correctly.
