:sendfile is fs specific aswell. it doesnt work on smbfs etc which
:seems quite weird.

    There are some fairly severe filesystem dependancies in the kernel
    sendfile implementation.  It uses the UIO_NOCOPY mechanism that
    UFS normally only uses when populating a buffer cache buffer.  What
    is needed here is a direct VOP interface to instantiate VM cache pages
    for a file.
