Tracking issue for MCP 1039: Test wasm in CI with threads & unwinding

This is a tracking issue for MCP "Test wasm in CI with threads & unwinding" (rust-lang/compiler-team#1039).

[!NOTE] Tracking issues are used to record the overall progress of implementation. They are also used as hubs connecting to other relevant issues, e.g., bugs or open design questions.

A tracking issue is however not meant for large scale discussion, questions, or bug reports. Instead, open a dedicated issue for the specific matter, link to this tracking issue and ping the MCP author. Alternatively, post in the Zulip stream linked from the MCP.

Discussion comments will get marked as off-topic or deleted. Repeated discussions on the tracking issue may lead to the tracking issue getting locked.
