When two clients call `newContextForReuse()`, either from multiple connections, or from a single connection + debug controller, they might end up creating two contexts or closing each other's contexts. Browser assumes only a single reused context, so it avoids problems by queueing operations. Exposed by flaky VSCode extension tests.
