You are correct, the writer will cache the new data, and the reader won't see
it until it's flushed out somehow. If you can arrange to have the writer sync
the filesystem before the reader reads the files, then it will get up-to-date
information.
Otherwise, if this is a problem, we need to make hostfs optionally synchronous.
