bug#18696: Emacs freezes for a while visitin Conf (.ini)) buffers

[Angelo Graziosi]

I have see this trying to visit Cygwin setup.ini files [*], for example:

  ftp://mirrors.kernel.org/sourceware/cygwin/x86_64/setup.ini


(it is a file of about 2.5 MiB).

After C-x C-f setup.ini, Emacs freezes (or hangs, if you prefer) and 
does not respond for a while (> 1 minute), CPU is at 80-100%. Then it 
works fine. Maybe it is processing the file but I wonder if this 
'freezing' is to be expected.

I have experimented this with Cygwin and MSYS2-MinGW64 builds.


Ciao,
 Angelo.
