Thanks for confirming, that is how I understood it...

How does this work? Is $GEMSTONE_LOGDIR is then set in the netldi 
environment based on your previous answer? Because in that case it will 
be the same for all RCP gems started per netldi... or does GsDevKit_home 
start a separate netldi per stone?
