On quit, vim shows that:
".netrwhist" [Not edited] --No lines in buffer--
This process usually takes 2s. How to turn this thing off?
--- Update ---
I noticed that netrw is installed as system-wide. Use the code below to disable all of those plugins.
se nolpl
let x = &rtp
se rtp-=$VIMRUNTIME
ru! plugin/**/*.vim
let &rtp = x
unl x
netrw. Rather than insert it in your question, it would be best to post this as an answer. – Gilles Jun 6 '11 at 7:06
