uv: An extremely fast Python package and project manager, written in Rust

Just a warning in case others run into it: on very anemic systems (e.g.: AWS T2.micro running Windows, yes... I know...) uv will try to open too many simultaneous downloads, overloading things, resulting in timeouts.

You can use ent ENV variable UV_CONCURRENT_DOWNLOADS to limit this. In my case it needed to be 1 or 2. Anything else would cause timeouts.

An extreme case, I know, but I think that uv is too aggressive here (a download thread for every module). And should use aggregate speeds from each source server as a way of auto-tuning per-server threading.
