NODE LANDS TEST RUNNER HANG FIX, OPENS TEMPORAL.INSTANT DEBATE

Node's test runner could deadlock on malformed V8 frames, but a fix landed overnight that unblocks the test suite from infinite loops.

The test_runner received a critical fix [1] that addresses a hang condition where incomplete V8 serialized frames in child stdout would trap the deserializer in an infinite loop. The fix makes the deserializer flush buffered bytes and resync on end-of-stream, restoring test execution flow. In parallel, a separate race condition plagued watch-mode inspect tests [2], where the interval-based child restart would collide with inspector session connections, causing random 120-second timeouts on CI. That flakiness is now tamed with tighter synchronization. On the feature side, an early-stage PR proposes Temporal.Instant support in fs.Stats and BigIntStats [3], but it's marked as experimental pending Temporal's finalization and default enablement, opening the door to community feedback on naming conventions and implementation details. Meanwhile, corepack ticked to 0.35.0 [4] in a routine dependency update.

Action items

→ Pull the test runner hang fix into your CI pipeline before next run nodejs/node [immediate]
→ Watch the Temporal.Instant PR for stabilization; weigh in early if your codebase touches Stats objects nodejs/node [monitor]
→ Update corepack to 0.35.0 at your next dependency refresh nodejs/node [plan]
