There is nothing "server" about change notification coalesceing. If any

to write() (if you read all events). This can easily be in the hundreds
a second for the entire duration of the download/copy. So, any UI that
tries to handle every change will more or less lock up.

You're talking about gio, I wanted to see what inotify would do in same circumstances:

I started inotify to listen to all the events on my desktop folder, then I took a large zip file (about 500MB) and started copying it to the desktop folder. There was no "hundreds a second" events, just 4 (four) events: IN_CREATE, then IN_OPEN, then IN_CLOSE_WRITE and finally (as the copy finished) IN_ATTRIB.

So inotify doesn't suffer from the Armageddon you describe, also it's fast. How come gio would be doomed/overworked in such a scenario and it's slow at reporting even 1 file change quickly.

Sorry I don't mean to be harsh but after these conversations I'm really starting to like inotify a lot more and disliking gio.
