this is a design document for things to come
probably meaningless to most

ipc - interprocess communication
copyless memory passing of asset data

minimize memory copies by storing struct in shmem heap

shmat 
       #include <sys/types.h>
       #include <sys/shm.h>

       void *shmat(int shmid, const void *shmaddr, int shmflg);

       int shmdt(const void *shmaddr);

// grab a page locked in memory - SHM_RDONLY if reader
shmat(31337, NULL, SHM_RND);
