// If the first number is non-zero, we errored out, and the element contains
// an error. We only returns error strings for errors that might be transient
// (e.g. we cannot connect to the server, or the connection dies), and crash
// on things that are almost certainly not transient (e.g. bad data on
// the wire).
//
// This function does double duty -- it both gets all the block services
// (the shard needs to know which ones exist to fill in addrs), but it also
// fills in the block services for the shard specifically.
