Just tested your script, there is definitely a memory leak.
I also ran into really weird behavior. Running your script
in tmux after starting and stopping an xorg session a few,
tmux completely froze in the session. Creating a new
window in the session was also completely frozen,
however this is only visually as commands still worked,
just showed a blank black screen.
Also unloading the kernel modules for
nvidia and nvidia-modeset (new as of 358.16ish) did
not free the memory.
