TartanLlama opened PR #12241 from TartanLlama:sy/yield-to-sync to bytecodealliance:main:

https://github.com/WebAssembly/component-model/commit/7479890cb506d0f8f687595a4d41361ff8a2a194 made blocking calls in sync contexts a trap condition. However, thread.yield-to is allowed in these contexts. https://github.com/bytecodealliance/wasmtime/commit/8992b99bf44eb8b91820586b85f58512fd4d7c1c implemented these changes, but also disallowed thread.yield-to. This patch relaxes the relevant trap check.

Testing added here: https://github.com/WebAssembly/component-model/pull/590
