Replace the startup-time
ps -U "$LOGNAME" -o pid,ucomm | grep ...check in the SSH module with a cheaper validity check based onSSH_AGENT_PID,kill -0, and the configured auth socket.The current check can block intermittently on process-list scans, making interactive shell startup time highly inconsistent on busy systems, in some cases taking multiple seconds.
Fixes #2140.
