There must be a fix for it...and I will find it.

Idling the engine does not do much to warm up the engine. If anything, it exacerbates the types of conditions that Dr. Evil was talking about above.
The fix is not to let it idle for so long.
Also, you don't need to let it idle for extended periods before shutting off. The only time that i would recommend this is when you have been towing a heavy load at high speeds.
