I can reproduce the issue on Debian amd64 Linux and it seems that for some
reason an additional wait() is necessary there on 64-bit Linux to get rid of the
last child. The easiest work-around is to simply run
selectChildren()
when you what to get rid of any zombies. I'll need to look at the code to
see if there is some clean way to handle this.
