We discussed this a bit back when we made --disable-max-function-depth.
It's just not the shell's responsibility to manage resources in this

zsh: segmentation fault (core dumped)  bash


The most I'd suggest is that we experiment with a MAX_FUNCTION_DEPTH
parameter that users could adjust when they have restrictive soft limits
or a small-memory host, etc.
