It may not be an easy port, as it freely uses lots of Python features,
including Jim Fulton's new-in-2.4 thread-local storage API (just like
the status and control registers in your HW FPU carry thread-local
state, the IBM spec has thread-local status and control data too).

A saving grace is that IBM's Mike Colishaw worked up thousands of
exacting test cases distributed in a plain text file format, and so a
broken implementation is remarkably easy to detect.
