Code review comment for lp:~allenap/launchpad/job-status-validator

Hi Aaron,

I forgot to ping you today about this, so for now this will have to
do. When you have a chance can you have a gander at this, especially
with respect to Jeroen's comment:

I'm very bad at doing pre-implementation calls, so I apologise in
advance if I've done something stupid because of the lack of that.

I'm back on Tuesday, so if you'd like to talk about it let's try to
talk then.

Thanks, Gavin.
