Duplicate file system events on Windows #171

Description

@norswap

On Windows, file system events are delivered multiple times. I expect this is due to the underlying technology.

However, wouldn't it be opportune to de-duplicate or at least group together these events? If the events are grouped in the same burst, they can be effectively manually de-duplicated. That would also be possible (albeit more arduous) if a timestamp for the change was exposed.

nsfw enforces a configurable "debounce" interval (default: 500ms) which basically means that bursts of fs events are delivered once per timer run.

watcher has a pollingInterval that seems similar, but fails to make any difference in my experience.

I think the difference might be that when the polling interval is over, watcher eagerly delivers events, whereas nsfw waits for an interval duration after received a new filesystem event (after idling).

Would it be conceivable to add such a debounce interval, or at least to expose the event's timestamp? Adding an automatic de-duplication parameter would be even better.
