Feature: add timer to close buffers that have'nt been visited for period

[asyncmind0]

I end up with 100s of buffers that I cant be bothered to go back and close.

I would like to expire buffers after a period of time.

Please give me some advise on how I can Implement this, I can code in python?

Maybe a timer object associated with each buffer that kills it after a period ? or A reaper process that goes through the buffers and kills them ?

Where do I plug it in?
