I don't know the reason why os/2 doesn't have fork() but it ISN'T because
there are multiple data segments.  Although they are now obsolete, there
used to be UNIX systems which ran on 80286 systems.  These systems allocated
a new segment each time you called sbrk().  They had no problems with fork().
