the pipe is used to wake up the other thread. but once its awake, it
uses information stored in memory (i.e. the slot).

its called RPC, and is normally combined with an Interface Definition
Language (IDL). it was hashed to death in the 1980's and early 1990's
and has turned out to be very much less than widely used. creating
stubs to pass <whatever> around so that one process can call a
function on behalf of another process has turned out to be much less
useful than people first thought it would be. your mileage may vary,
of course.
