Thanks Joe!

This is really, really cool.  We are currently below 40% code coverage,
partly due to a LOT of PIDL-generated code that we don't run, but we
also should be really proud, we do cover a lot of code!

Tasks from here are:
 - finding code that we think is tested but doesn't show up (and fixing
that one way or the other)
 - removing dead code (I'm going to try with callcatcher again)
 - adding new tests!

I'll gladly review any patches towards the above,

Andrew Bartlett
