Problem

I used the command cargo install cross, and while downloading the crates index (few minutes), my CPU fan started making noise. After checking, a CPU code was at 100% usage.

Steps

1. Run cargo install cross (any anything that acually updated the index)
2. While waiting for the download to complete, check the usage

Possible Solution(s)

Maybe the display is updated each time a chunk of data is received, which triggers a lot of updates for a long time, in case the network connection is slow.

Notes

Output of cargo version, running on macOS 10.14.6:

$ cargo version
cargo 1.49.0 (d00d64df9 2020-12-05)
