We need to capture data on corner cases

Our code is full of quirks/hacks that catch obscure real-world cases.  Most of 
the time, the code is just clutter.  On the other hand, if your environment 
triggers that case, that small chunk of code is wonderful.

I think we need a structured way of collecting and documenting this sort of 
thing.

Should we put a big comment in the code?  With a stylized tag so we can find 
them all.  If you are working on other stuff, that's just adding to the 
clutter.

Should we collect the descriptions in another file and add pointers both ways?
