The first few slots were reserved specifically for uses like this.
I may have been extravagant or greedy -- two might serve as well as 
five, and there's no reason you couldn't change the reserve-count 
in any release; it doesn't affect the ABI.  Five slots seemed like
the most arbitrary smallish number sufficient to help provoke their 
use.  Do comment it.  

Slot 1 might be used for some kind of multi-thread purpose.  I have 
no clue what any other reserved slots might someday be used for, if 
anything.
