Safer threading for performance improvements was part of it, as I understand.

Imagine how much faster it will be with threading!

Rather think of cp, mv, install, backup. Copying files faster is still an ongoing effort, also in gnu coreutils

When I want to do stuff in parallel at the OS level, I rather user processes and e.g. GNU parallel.
