I'm not sure this is a good idea: it allocates too much memory from
the DPMI server.

Did you see whether the allocated blocks use high addresses in this
modified version?  If not, you indirectly worked around the problem by
feeding `sbrk' with the low addresses, like in Unixy sbrk case.

It would be nice to know how does this happen.  Perhaps that will
unlock the problem.
