Just out of curisoity (no I cant spell), what forces there to be a limit
on max shared mem sizes in the first place.  I *THINK* that 2 processes
can mmap() a file with MAP_SHARED and get any size of shared memory region
that they want.  If this is true, what is different about the shm*
functions?

Thanks,

Jim
