If you run your 2.x server with one process, then you won't have to
worry about shared memory.

If the table is not going to be changed, then you should probably set up
the table during an Init function. It will then be inherited by all of
the children. If you need to make an update at any time after the Init
function, then you'll have to use shared memory.
