Comment (by mindctrl):

 I'll have to measure before and after to confirm, but a cursory look at
 Weston's PR seems to reduce meta db ops by a meaningful amount.

 > * doesn't slow down if the browser window loses focus
 > * I can't find any code indicating a slow down due to a lack of
 activity, I've had a browser window open in the background for around ten
 minutes while typing this and it's still firing each second

 Probably should be a separate ticket, but I can confirm this behavior. It
 would be nice to include some throttling detection for when browsers lose
 focus and/or don't have typing/activity in some period of time. I left a
 couple clients open for ~7 hours for testing and this caused over 230k
 post meta writes.
