>Requests a shared memory area of the specified size to use for transferring
command arguments. This is faster but less portable than the standard BSD
sockets method of communication (and of course will only work if the client
and server are on the same machine). Apart from the initial allocation of
the area using this call, the use of shared memory is completely
transparent. Additionally, if the allocation fails we silently and
automatically fall back on socket communication. It is safe to call this
function even if shared memory support is not compiled in; it will simply
do nothing.</P
