File streams

According to libuv folks, the most reliable way to do asynchronous file I/O is blocking read(2) in a threadpool. Although Windows has IO Completion Ports, they fall down in enough cases they are largely not used. Regardless, we want to support read(2)-in-a-threadpool models, so this section assumes files are a good instantiation of that model, and analyzes how readable byte streams work in that case.

Reading a file byte stream into an ArrayBuffer

Given a file readable byte stream with a known size, read the entire thing into memory:

async function file_exact(fileRBS, knownFileSize) {
