Summary: public We're seeing related crashes. The diff has no tests, the perf tests weren't conclusive, and the person who'd be supporting it no longer is available to work on it. We can try this again later in a less rushed manner with proper perf testing. Reviewed By: davidaurelio Differential Revision: D2696615 fb-gh-sync-id: 3b6814ac12af19516146d5c42d2add8321b10db5
