This may be a bug in your shell. If it's not > a bug in your shell, then it's a bug in kernel (probably in > fork_exit). In this case PPID == 1, so even if the parent process failed to reap the child, init should have reaped the mtvp process when the parent process exited. The "ZW" state looks suspicious. I'd expect to see just "Z". Maybe that's why the process isn't getting reaped.
