This seems awkward to me.  I feel like ls -ld /proc/PID/{cwd,exe}
should probably show something distinctive instead of "/".  Maybe
readlink() should show "[failfs] /" or similar?  Both admins or
developers trying to see what's going on and CRIU might want this.
IMO it's too bad that we don't have a nicely parseable readlink output
for oddities like links to deleted files, but oh well.
