A shared memory map segment?  Seems like that might be better.  Maybe
have the appserver create a chunk of mapped, shared memory, then have
the app send a message to the server requesting a memory region of n
bytes.  The appserver can pick a section of it's memory map of size n,
and send back the location, at which point it can be mapped by the app.
App can write to that, then send a message to the appserver saying it's
there.
