Yes; etc/Init.sh uses:

	tmp=/tmp/grass6-$USER-$GIS_LOCK

Init.sh initialises GIS_LOCK from $$, which is the PID of the shell
process running the script. That should work in any Bourne shell; it
won't work in other languages, e.g. PHP. Presumably the PHP script is
initialising the environment itself, and not using Init.sh?
