Hi Michael,

Apologies for the delay.  I started a new job the day after I sent this

I'm honestly still not sure.  Maybe it's a simple test but I'm still
scared of completion tables from a bad experience a few years back.
I've just made some modifications so the same logic is in place.

Thanks for fixing that!

This is being violated in the current tests by the stubbing out of
`soap-invoke-internal'.  Please see the first attached patch where I fix
this.

I wanted a clean wrapper around the cache functions to make it easy for
future testing.  Specifically, I want to add a feature so the cache
survives an emacs restart.

I don't believe I have push access to the repository.

Thanks for reviewing my patches!
