// When talking to the nodejs runtime we have three parties involved:
//
// Engine Monitor <==> Language Host (this code) <==> NodeJS sdk runtime.
//
// Instead of having the NodeJS sdk runtime communicating directly with the Engine Monitor, we
// instead have it communicate with us and we send all those messages to the real engine monitor
// itself. We do that by having ourselves launch our own grpc monitor server and passing the
// address of it to the NodeJS runtime. As far as the NodeJS sdk runtime is concerned, it is
// communicating directly with the engine.
//
// When NodeJS then communicates back with us over our server, we then forward the messages
// along untouched to the Engine Monitor. However, we also open an additional *non-grpc*
// channel to allow the sdk runtime to send us messages on. Specifically, this non-grpc channel
// is used entirely to allow the sdk runtime to make 'invoke' calls in a synchronous fashion.
// This is accomplished by avoiding grpc entirely (which has no facility for synchronous rpc
// calls), and instead operating over a pair of files coordinated between us and the sdk
// runtime. One file is used by it to send us messages, and one file is used by us to send
// messages back. Because these are just files, nodejs natively supports allowing both sides to
// read and write from each synchronously.
//
// When we receive the sync-invoke messages from the nodejs sdk we deserialize things off of the
// file and then make a synchronous call to the real engine `invoke` monitor endpoint. Unlike
