If Exec ever gets its act together and starts >using the MMU, your stack would be private memory. Wouldn't it be nice if there were a MEMF_PUBLICLY_READABLE memory type? The idea is that any process can read that memory, but only its owner can write to it. Stacks could use this type of memory by default. And a MEMF_READ_ONLY would be useful (for things like sharable libraries), if someone could work out a semantics that allowed it to be written into once, sort of like the A1000's WCS. I dunno if Motorola's memory management hardware would support any of this. -Peter Schachte pds@quintus.uucp ..!sun!quintus!pds
