Duplicate Python/C code will probably become more common.  Even if the 
Python is not used for prototyping (which I believe it was for heapq), 
it serves to document the intention of the C code and to be a ready to 
go version for non-C implementations.  And it can be used as a basis for 
modification by Pythoneers who want slightly different behavior.
