pgrep fails to find ssh-agent

Running openssh 7.7 and procps-ng 3.3.13 on archlinux.

The /proc/pid/ns folder of ssh-agent is owned by root after starting it up (¿some kind of security improvement?), so pgrep is failing (or that's my guess from looking at the strace output).

Maybe the /proc/pid/status file can be used as a fallback for checking the user?
