Setting a process to be a local "Grim Reaper" when the program that it is running does not handle being notified about children that it did not fork in the first place can cause some programs to misbehave or even crash.

Setting a process to be a local "Grim Reaper" when the program that it is running does not itself wait for child processes, or only waits for specifically identified children that it knows about, can cause the process table to fill up with "zombie" entries.
