vjrj fbb746fba2 fix(subsUnion): move geo-union math to a worker thread, not just yields ... The previous fix (yielding to the event loop between turf.union calls) was not enough: once the merged polygon gets complex with thousands of subscriptions, a single turf.union call can itself take seconds, and yielding between iterations doesn't help when one iteration alone blocks that long. Confirmed in staging: the site was still fully unresponsive (Cloudflare 524, curl hanging 2+ minutes, healthcheck failing) while a recompute ran. Validation/decoration (addNoisy/noNoisy, cheap) stays on the main thread; the actual circle+union chain now runs in a worker_thread (private/workers/unionWorker.js, plain CommonJS so meteor build copies it verbatim instead of compiling it) so the main event loop serving DDP/HTTP is never blocked by it, regardless of how slow any single turf call gets.		2026-07-30 07:48:17 +02:00
