The underlying issue does not affect our CI hosts, but is an issue on my
development machine (Arch Linux). In particular, this affects the vanilla
configuration of Docker on systemd, which has effectively no limit:
11400a3f5a/pkg/docker-engine/common/systemd/docker.service (L31)
I hope this saves future generations some precious hours of their life.

# A too high maximum number of file descriptors (with the default value

# inherited from the docker host) can cause issues with some of our tools:

|
# - valgrind crashing: https://stackoverflow.com/a/75293014

|

# on their machines may run into this (e.g., on Arch Linux), so warn them.
