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,
