parent / child processes

Process A creates another process B. Process A then dies, but process B still has the PID of process A marked as its parent process. Later on, a process C starts and is randomly assigned the PID that process A was originally assigned.

Are there any security or other implications of this happening?

Windows is better in this regard:
'nothing relies on that information'
"process continues to exist as a "zombie" process until the child process is done as well"
