Oh...I see. What you want is synchronization of
changes to the recentf-save-file.
No, my functions do not do that.
What you want may be slightly more difficult.
I do not know if emacs has an efficient mechanism
(i.e. not based on polling) to monitor changes to files on disk.
One approach may be:
1. Before showing the entries to the user the recentf package could
check the timestamp of the recentf-save-file. If
it is later than the time it was last read it could reread the file.
2. Similarly Before writing out the entries to the recentf-save-file
the entries of the current session should be merged with what is
on the disk.
