Description

I would like to know when items are dropped from sliding or dropping buffers, so that I can do things like logging and keeping metrics.

The attached patch has one possible mechanism for doing this, by adding an optional second argument to sliding-buffer and dropping-buffer - a one-argument function that will be called with dropped items.
