I think I acknowledged inability to handle knfsd... just don't use
knfsd, then. Its not like nfs is critical for communicating with
Windows, right?

That is still better than proposed solution here -- TALPA breaks with
mmap, or when someone does read too soon after write. 

Marketing "antivirus" system that is racy be design seems to deserve
some manure.
