Cracked carbon and other modern misfortunes: Bikefanclub.com

I considered adding this as a reply to the Carbon bars thread but decided it would be terribly wrong to usurp Craig Calfee's name on the index. (Head nod to the south, bent knees on office carpet, etc.)

Here is my question. I have a vertical crack in my carbon seatpost, starting just where the clamp was originally located on a different frame. When I transferred this seatpost to my Tetra Pro the height adjustment allowed the crack to be below the clamp and my bike shop said not to worry since it wouldn't be stressed. Now I am wanting to raise my seat height and the crack is straddling the clamp, as well as encountering some slippage which led me to "remember" the crack and actually take a look at it.

How should I respond? Run, run like the wind to get a new seatpost? Figure since its vertical the worst that can happen is it keeps growing (or grows vigorously) and the seat clamp falls off while I'm riding? Carry a metal tube with a pillow glued on the top to put over the post if the seat does fall off during a ride? Get a life and use common sense?

Thanks
