alexcrichton opened PR #4354 from component-lock to main:

This commit updates the management of the may_enter flag in line with
WebAssembly/component-model#57. Namely the may_enter flag is now
exclusively managed in the canon lift function (which is
TypedFunc::call) and is only unset after post-return completes
successfully. This implements semantics where if any trap happens for
any reason (lifting, lowering, execution, imports, etc) then the
instance is considered permanently poisoned and can no longer be
entered.

Tests needed many updates to create new instances where previously the
same instance was reused after it had an erroneous state.
