multiprocessiing default mode on POSIX will result in Eliot logging configuration being inherited by children. This is not ideal, since it's inconsistent across multiprocessing modes.

os.register_at_fork would allow fixing this. However, this is not strictly backwards compatible...

Windows does not support fork at all, it's a Unix-specific concept. I strongly recommend never using fork mode even when it is supported: https://pythonspeed.com/articles/python-multiprocessing/
