If this does not happen on Debian-based OS or macOS I guess it could be a glibc or maybe even a OS bug. This doesn't cause test failures but makes the output quite noisy. I have a few leaked descriptors for a while on Fedora when running test-all, also on previous Fedora versions. -- https://bugs.ruby-lang.org/
