The underlying reason seems to be a substantial difference in the hosted
runners that execute these Dockerized jobs: forcing the PID limit of the
container to a high number lets the jobs pass, even when running the
complete matrix of all 13 Dockerized jobs concurrently.

Is the "reduce" in the title accurate?  The above description tells
me that what you did was to "raise" the PID limit (i.e., forcing the
PID limit to a high number), presumably because the default PID
limit is way too low for the tests to pass?

You are right; The subject is wrong. The patch raises the limit from
the hosted-runner default to 16384. The subject is a left-over from a
hypothesis that my experiments refuted.

v2 will retitle to "ci(dockerized): raise the PID limit for private
repositories". No code change: 16k remains the sweet spot between the
failures we saw at 8k and the slow runs at 64k.

Ciao,
Johannes
