mmapping with MAP_PRIVATE

Is it true that if I mmap a file with MAP_PRIVATE (so that the file is
copied to memory when you attempt to write to the mmapped area), you have
to physically/virtuall have a memory block large enough to contain the
mmapped area? I noticed that I could mmap 100 megabytes of a while when I
used MAP_SHARED, but couldn't if I used MAP_PRIVATE. Smaller sizes worked
great with MAP_PRIVATE too.

I think this should be fixed, as it would make programming databases much
easier ;). And it is a bug, right?
