(* This module maintains a cache that can be used to map
an Os.fullfingerprint to a (Fspath.t * Path.t) naming a file that *may*
(if we are lucky) have this fingerprint. The cache is not guaranteed
to be reliable -- the things it returns are only hints, and must be
double-checked before they are used (to optimize file transfers). *)
