Re: Tramp with global-auto-revert-mode.

[Luc Teirlinck]

I plan to commit the following shortly.  The problems with
auto-reverting remote files can occasionally become so bad as to make
Emacs unusable.  The crash is not the only problem.  Maybe one could
discuss setting the default back to t.  But people with a slow
connection definitely need a way to disable auto-reverting of remote
files.  So the option seems to be definitely needed.
