I had an issue once where I had some auto-complete things setup for  
bash that took a long time to load, slowed down all my commands.  
Allan helped me set it up so it only activated when a interactive  
shell was used. I'd tell you how he did it but it was on my old  
computer, not sure I still have the file.
