Before starting VirtualBox, I always check to ensure all cpu/memory intensive applications and services are stopped. Usint htop sorted by RSS showed /etc/X11/X was using 150M for RSS. After restarting the x server, it was back down to 32068 bytes for RSS. When x was at 150M Uptime: was 1 day, 17:53:29.

Memory is given back to OS when freeed. It's just keeped in free memory pool of X11-server. It would be a buf if RSS would keep growing.
