Hello,
1. emacs -q
2. (setopt icomplete-in-buffer t)
3. M-x icomplete-mode
4. M-x eshell
5. cat very_large_file.txt # I'm using an 80k line log file
6. ls <TAB>
7. Try to use C-, and C-. to cycle through the completions.
=> Emacs basically locks up.
The buffer being large should surely not affect icomplete-in-buffer in
this way. It shouldn't need to care about all the rest of the buffer.

Strangely enough, I can only reproduce this on GNU/Linux, but not on
MS-Windows.
Profiling seems to indicate most of the time is spent in
completion-all-sorted-completions and in GC.
