Guy Harris said something that made me see red:  the TLI uses state 
information that is kept in userland.  Does that mean that it takes
parameters from userland and then operates on them in kernelland
or doe sit mean that it uses userland dataspace to keep some state
variables that the user can change between system calls to get data
to or form the stream?  If so, it is a potential source of random
havoc or invidious hackery to accomplish amazing ends.  In short, I
am asking:  is this a security or integrity breach ot not?
