I have more than one streaming feed > plus UUCP, gated FidoNet traffic and NNTP readers, It is not a legitimate use to extended a mapped file without remapping it. Specifically, if the mapping goes from a frag to a larger frag (or to a block) as a result of being extended, it's obvious that you should expect problems. That this works on SVR4 and SunOS is an artifact of their VM system cache being device/block based.
