Yes, that worries me a bit, too.  I have the same worry with the idea
of rewriting the entire decimal module in C.

The Deccoeff type is very simple, though.  It would be easy to create
a pure Python version of it, and then do something like:

try:
    from _decimal import Deccoeff  # try to get C version
except ImportError:
    from deccoeff import Deccoeff  # else use Python fallback code.
