According to "top", the used memory by zsh was > up to 583 MB. And nothing was actually removed. I can reproduce the memory consumption with a 7210-file Maildir, except that my kernel does the right thing and kills the runaway zsh. If I abort the rm before it OOMs, zsh will continue to take up a large amount of memory until it exits.
