OOM crashes #5085

Let's reevaluate this after #5041, though it shouldn't be leaking per se. In Haskell can we detect memory pressure and reduce our cache sizes? |

Describe and demonstrate the bug
I don't know a simple way to reproduce this. But for the last couple of hours I have doing a lot of the following commands on the nimbus codebase while searching for unused code and code that has been upstreamed to libraries:
ls
dependents
delete.term
delete.namespace
view
Often I'm calling these with numbered args from
ls
anddependents
output.2 or 3 times my computer has frozen and my fans have gone full throttle (presumably from CPU usage). One time I gave up and did a hard power reset of my computer and the other time my OS had killed my tmux process when I returned to my computer ~10 min later.
I'm guessing that there is a memory leak and that I could get this to fail more gracefully by setting a max memory limit on the Haskell runtime. But ideally this wouldn't be necessary.
Environment (please complete the following information):
