Must large pages be allocated this way?
At some point I would like to see code that mmap's large amounts of
data (over 1GB) and have it take advantage of this once the kernel is
potentially extended to deal with mapping of large and/or variable
sized pages backed to disk.
Also, some scientific applications will malloc(3) gobs of ram, again
in excess of 1GB, is it unreasonable to expect that the kernel will
notice large allocations and try to provide large pages sbrk in
invoked with suitable high values?
