nit: Should this return an interface that gets cast to the EvalTracer?
Nevermind, this appears to be the interface

Does this handle a nil tracer?

Yes, I've added a test for this case as well just to be sure.
I'm not sure that 503 is the exactly the correct http response though--open to suggestions on better responses there.

I don't think 503 is a good choice, isn't it supposed to be fore temporary conditions? I'd probably go with 501 or 500.

It looks like txnGroupDeltas needs a RW lock.

I created a child PR while going through this PR to add some additional handler checks for my own sanity: Eric-Warehime#7
