I believe the list of incompatibilities and kludges and the subsequent 
comments in the following file give the gist of the problems:
http://svn.python.org/projects/sandbox/trunk/decimal-c/_decimal.c

Basically, while it makes a lot of sense to move the *arithmetic* to C 
(as Mark mentioned in his other post), there's a lot of ancillary stuff 
related to flags and exceptions and context handling that is much easier 
to handle in Python.

Cheers,
Nick.
