I noticed that gosnowflake added https://github.com/99designs/keyring as a dependency and, unfortunately, this library has an outstanding bug which can lead some Linux systems to create zombie dbus processes. This issue was observed initially when importing the Apache Pulsar client library into Benthos as described here and it's triggered in one of the init() functions from github.com/99designs/keyring. One workaround that I identified is to set DBUS_SESSION_BUS_ADDRESS=/dev/null on process startup.

I tried to reproduce it in a Docker container, but didn't succeed yet, so I opened this issue to raise awareness and I'll share detailed reproduction steps at a later time if I get more time to poke around with it.
