 *  The following simple program happily allocates memory until my
 *  machine dies. Although i should have no more than approx. 150
 *  MByte (disc + ram), it allocates more than 300 MB before
 *  hanging.

This is what I got from running Stefans program. (I had to undelete
the paging file). But the program claimed to have allocated 39.999 MB
of memory. Not bad for 8MB RAM plus a 1MB page file.

BUT - It quit on an exception 13 from the memory manager (QEMM),
which I think means the memory management got corrupted. My feeling
is that DJGPP has got its own memory management system outside of
whatever bounds it is allowed: in this case, quite probably it has a
page table or something that has filled the 5MB of extended memory
available.
