I think it has one mapping, which is set to "map ahead" at creation, beyond immediate needs. When it gets a request to map beyond the current mapping, it discards the current mapping and makes a new one. At least that's what I think happens. Somebody must have written it - it looks debugged and solid - but I don't recall doing it! I tried making amore sophisticted mmap cache over the weekend. It is surprisingly hard. Peter
