It depends. If the array is not accessed all at once, the OS needs only to 
set up the virtual memory maps and then page fault in the pages as needed. 
If the array is larger than the amount of memory that the OS would like to 
allow the program to keep in memory it could get even worse as it will start 
paging stuff out before the app even gets to main() (OTOH IIRC OPTLINK won't 
allow that big a static array).
