Heap out of memory when bundling

[sayzenberg]

Environment

"@haul-bundler/preset-0.60": "0.18.0",
"@haul-bundler/cli": "0.19.0",
"@haul-bundler/core": "0.19.0",
"react": "16.9.0",
"react-native": "0.61.5",

Description

I'm migrating our app from using the legacy version of Haul to the new one, and running into an issue while bundling our app, where it always seems to run out of memory on the heap unless I pass a larger max-old-space-size value to Node. Is there a good way to figure out why this is happening?
