I noticed that when I launch an app from WBAR, a shell process is created and remains alive.
This is wasting RAM!
I'm having the same problem with JWM. I added a button in my jwm tray to launch a shell
<TrayButton label="$">exec:aterm +tr</TrayButton>
Works fine, but when I push this buttton, it creates the aterm and TWO shell processes.
Looking for solutions to minimize amount of processes!
