David, thanks for fixing the problem about `recentf-cleanup'
signalling an error.
But I'm still not sure if it's not a good idea for `recentf-cleanup'
to call `file-readable-p' on remote files _at all_. The reason is
that it can be a *very* slow operation.
For example the following takes nearly 5 minutes for me [1]:
(file-readable-p "/address@hidden:/usenet/control/alt/alt.religion.emacs.gz"))
Now imagine if you happen to have a few of these files in ~/.recentf
-- if your turn on recentf in .emacs, this could delay Emacs startup
for many minutes.
[1] I don't think ftp.isc.org is particularly slow, it's just a big directory.
