I'm using ReadDirectoryChangesW() to read a filtered stream of events from the USN journal. I've not noticed any reliability problems. Technically, the kernel API can always drop events, but whether that is a kernel can't keep up problem or the daemon application not servicing the event stream fast enough doesn't really matter. The API does know if/when events were dropped. And the FSMonitor daemon guards against that and forces a "resync", so the "git status" client is advised to do a normal scan, so the output is correct.
