If you want to have the mmap'd memory show up as something other than
byte[], then you'll need to do some alignment computations here:

David> X    array = (jbyteArray) (data - sizeof *array);

In the current CVS, `length' is const and you can only assign to it
via a const_cast.  Here's the line that would have to change:

David> X    array->length = (jsize) statb.st_size;

I made this member const because it is conceptually more correct,
reduces the possibility of introducing a bug, and might make it
possible to optimize a little better in some situations.
