Thanks for the lead.  That looks pretty good, although he didn't deal with 
optional properties, and the comments completely trash indentation, which makes 
it a bit hard to decipher the various commenter's fixes for that.

Hey Nick, you care to revisit this and make a version with *props that's robust 
to optional fields?

Also, just like the autoretry_datastore_timeouts recipe that everyone had to 
copy into their code and eventually moved into the SDK, I still think this 
ought to be built-in to the SDK, since it's clearly something everyone needs to 
do, and most people probably don't, and it is pretty hard to get exactly right.
