a) and c) don't look consistent with the two SIGCHLDs logged in your
trace (310 and 314).

The hint about non-empty cgroup + gap in PID sequence [1] suggest that
the parent and child are not the only two processes of the service.
I suggest checking the cgroup.procs of gnome-keyring.service (you can
find cgroup path e.g. in `systemctl --user status
gnome-keyring.service).

HTH,
Michal

[1] Can be parent's threads or concurrently spawned processes elsewhere in
the system.
