If Eshell calls `process-file', it shall bind `process-file-side-effects'
to nil if appropriate for the given command.

Furthermore, Eshell might bind `remote-file-name-inhibit-cache' to
something which helps. The default value (10) seems to be very conservative.

In case Eshell needs to clear the cache for a given directory, there is
`dired-uncache'. Contrary to its name, it is not restricted to dired,
but of general purpose.

Best regards, Michael.
