However, I am still investigating to pinpoint the problem more
precisely. I am pretty sure now that file-attributes is not the
problem. I artificially delayed stat on the remote end such that
I was able to start different foreground actions with defined
interleaving when file-attributes was called from a sentinel. It
appears that Emacs is blocked completely during file-attributes,
such that it is impossible for the user to trigger anything. This
rules out the scenario that I described in the previous message
for file-attributes. I haven't checked delete-file, but I have
hints that file-truename is problematic. Maybe there is a simpler
fix by ensuring that the remote actions inside file-attributes
block Emacs?
