Its come to my attention that my implementation of ptrace has a small bug
that complicates the debugging of programs that fork other processes. The
following context diff fixes this. Apply it to mm/forkexit.c using patch.
Thanks to Kai-Uwe Bloem whose bitnet address is inaccessible to me for
pointing this out.
