The accompanying patch is Copyright Sychron 2001

This patch implements process adoption; fields have been added to the
task structure and logic to the process creation/destruction (fork and
exit) functions to maintain a link to each process's nearest living
ancestor.

The traditional behaviour of the parent pid (set to 1 when the parent
dies) does not cope with daemons which outlive their (short lived)
parents.

Refer the annotation in sched.h for details.
