wait3 emulation in SYSTEMV ?? - (nf)

[jh at pcsbst]

It is not true that a process id is not unique, even for a
dead process in the zombi state.

In AT&T System V.[23] a zombi process keeps its process id (pid)
until it is really eliminated by wait() (or ignoring SIGCLD).
Thus, the process id is not reused when creating a new process
and the technique for a pseudo wait3() in SVR[23] should work 100% ok.
