I think that I'd be hesitant to introduce too much variation between production and test environments when it comes to processes. It's a major advantage if you can test your processes in the test tier, then run those same processes verbatim (key-for-key) in production afterwards.

I feel like a short timeout is likely to cause more frustration in the trenches than what it's worth, for anyone who spends any significant amount of time troubleshooting production systems. Often you have multiple windows open and switch between them... an aggressive timeout really makes that much more difficult.

Personally, I think background color is your best bet. Only difference from Alfredo's suggestion would be that I'd prefer having it be controlled server-side rather than relying on each engineer to setup all their terminal connections correctly. Not to mention that you could get the *wrong* bg color if it's client-side and somehow somebody ssh's between tiers.
