If you tend to obsess over the number of open Emacs buffers, worrying about performance, here’s some good news
"Operation finished; killed 543 buffers"
There's about 400 left still. #Emacs at 29+ days uptime. Still snappy and responsive.

I’ve never come close to that many buffers and I don’t know what his machine configuration is like but you have to admit that that’s pretty impressive.
