Not much more than that.

As you said the problem is to decide who has the duty to remove the file
at last.  If each Emacs deposes a file says .foo.eln-pidxxx for the
whole time is using foo.eln should be easy for the last Emacs to
understand it is really the last and has to do the clean-up in the case
foo.eln was renamed in foo.eln*whatever

I think it could work. (?)
