Maybe it's worth to mention, that `tramp-cache-inhibit-cache' does
something like this:

  tramp-cache-inhibit-cache is a variable defined in `tramp-cache.el'.
  Its value is nil

  Inhibit cache read access, when `t'.
  `nil' means to accept cache entries unconditionally.  If the
  value is a timestamp (as returned by `current-time'), cache
  entries are not used when they have been written before this
  time.

If we use a relative time (number of seconds the cache is valid), and
generalize this variable outside Tramp, it could serve our purposes.
