Yes [#41642](https://github.com/JuliaLang/julia/issues/41642)

> The main reason for the divergence is that Julia’s libuv fork has a significantly more flexible event loop model that allows using libuv from multiple threads efficiently.

Glad to hear this. That's impressive.

Thanks for the bug report (assuming that’s you that filed it). The change that broke this was made first in Julia’s libuv fork but is being upstreamed into libuv main. It simulates UNIX chmod functionality on Windows, which is (apparently) tricky to get right across all versions and all corner cases. Supporting that correctly has been an outstanding TODO in libuv for a long time — what you’re seeing is Julia driving the development of libuv and therefore hitting the bugs first.

This issue was reported seven days ago and is now slated to be fixed in the next release of all affected versions.
