I'd probably plead "too platform specific" but I've already got some
platform-specific stuff in there like TCP_INFO so I probably cannot hide
behind that. Particularly if I ever do make "native" WSA calls for
Windows...
Until now I'd not thought of vmsplice/splice though - only sendfile for
zero copy, which should be there for TCP in the form of the TCP_SENDFILE
test (unmigrated, so none of the omni output selection is available)

I'll start to ponder, without promises.
