Build jobs outputting loooong lines slowly may delay other server responses?

Hi!

This is maybe more a PR for me than for you, but (haven't yet made a specific test for this) I've got the feeling that laminard will not answer further API requests (from frontend or laminarc show-running etc.) while running jobs are doing an initial git clone. As I usually have 16 jobs running in parallel, I initially thought that it's just I/O bandwidth or something like that.

However, my current thought about it is that it's possibly the long output of git clone without a \n. Once the current round of cross-building Linux powerpc kernels is over, I'll create a test job (output stuff slowly without a \n for a long time) to verify my educated guess.

Thanks,
Jan-Benedict

For reference, I tested with this job:

#!/usr/bin/env bash

for i in {1..300}; do
        printf 'This is some output with another %%i: %i\r' "${i}"
        sleep 1
done
printf '\n'

...but couldn't reproduce this issue, so I'll close this PR.
