Implement AgentCanSuspend check for Atomics.wait#2364
Merged
Conversation
Add Options.AgentCanSuspend property and enforce DoWait step 8: throw TypeError when the agent cannot suspend. The test262 harness now configures this per-test based on CanBlockIsFalse/CanBlockIsTrue flags, removing the need for the CanBlockIsFalse exclusion.
