What is the state of things here?  I'm a bit lost in the discussion :)

You said that decompressing the zip file takes 74 seconds with Guile as
it is now.  What if you change to use Guile's arithmetic instead of
fxops?  That would give is a good baseline so that we can know how much
overhead the fxops have.
