My understanding is that zombie processes occur when the task dies,
but the parent hasn't called waitpid(...) on that process yet.
The Linux kernel needs to keep track of the process so it can return
the processes status, in case the parent does call waitpid(...).
If you see a zombie persist, then the parent process is probably slow
or buggy, as it has not yet done the right thing.
Of course, you could argue that the penalty is small, but IMHO, it is
still a bug if the parent doesn't clean up after its children.
