Environmental variables have caused some of my more troublesome debugging experiences: 1) On Windows, VisualVM not being able to find the IntelliJ IDEA process I had running. This happened because IDEA was started with Launchy, which had a different TMP directory set, because I used both RDP and the Console, or something. 2) On Linux, ibus IMEs not working at all in my browsers; happened because I was starting them in a tmux, and the tmux server was started in my previous login session, so the DBUS_SESSION_BUS_ADDRESS in the tmux was stale.
