Summary: Watchman, the only consumer of subscribeStreamTemporary today, does not use the published JournalPosition values. Instead, it waits a bit, and calls either getCurrentJournalPosition or getFilesChangedSince. This is a good thing, because write traffic to a filesystem can easily exceed the rate at which Watchman (or even streaming Thrift!) can consume it, spiking memory usage and degrading performance. The next diff in this stack will take advantage of this clarified communication protocol to reduce edenfs memory usage under heavy write traffic.
