alexcrichton opened PR #14556 from alexcrichton:more-lockdown to bytecodealliance:main:

This commit updates the poll_until event loop to stop harder once the event loop encounters a trap. Previously it was still possible to execute preexisting wasm tasks through the event loop, for example, when the purpose of the lockdown-on-trap is to halt everything and drop everything on the floor. This is a small fix in the main event loop plus a minor adjustment to turn a bail_bug! into a normal bail! since it's expected to be possible to hit.
