desktop.el has a lock mechanism that is independent of external
programs. I'd prefer such a solution. Maybe the lock mechanism in
desktop.el could be made more generic (and moved from desktop.el to
simple.el/files.el?) so that other packages could use it without
duplicating the code (and loading desktop.el).

Prompting could offer this as well.
