Try do it more than 4 times, like: M-> M-v M-v M-v M-v M-v.
The delay often happens at the first M-v, but not always.
The delay is about 5 seconds on mac OSX (cpu: 1.4GHz), and is about 2 seconds
on linux (cpu: 2.53Ghz).
Or try to input some text (like newline chars) at the end of buffer.
I input a newline at the end of buffer, and emacs didn't respond about 2
seconds on linux.
After apply the patch, there is no delay after yank.
