Horah! I understand it - thanks for clearing this up - the magic
figures are the memory addresses 78000000-7FFFFFFF. Taking one from
the other gives 7FFFFFF then converting to dec gives 134217727 and
finally dividing the result by 1048576* gives 127.999999 or 128MB when
rounded up.

* Number of bytes in a MB but I'm sure most of you know this.

Excellent
