SHFS => "foo changed on disk" warning

[Felix E. Klee]

Hi,

I mounted a remote directory from a server PHI with SHFS (allows
mounting of directories that are accessible through SSH) on my client
DONALD by using the command "shfsmount phi: ~/mnt/p.uk". However,
editing files in that directory with EMACS 21.2 is problematic. An
example: 
1. I open a file "~/mnt/p.uk/foo" with "C-x C-f". 
2. I edit the corresponding buffer. 
3. I save the file. 
4. I try to continue editing "foo" but get the warning "foo changed 
   on disk; really edit the buffer? (y, n, r or C-h)".

How can I find out why I get this warning?

BTW, I already had the idea that the problem is due to bad time stamps.
However, when I save "foo" it gets the current time of DONALD as a time
stamp (the client) and not that of PHI (the server). In addition the
clock on DONALD is ahead of that on PHI. Therefore, I doubt that
time stamps are the issue.
