Describe the bug
I've declared 395 resolves, and I'm trying to run mypy. Running pants check :: fails with OOM. The memory consumption >50G quickly escalates during Resolve coarsened targets phase, flag --pantsd-max-memory-usage doesn't help.

Pants version
pants_version = "2.19.0"

OS
Ubuntu 22.04
