Does it block? I thought it would just return false?

Fixes a race condition where a sandbox kill arrives after a sandbox has successfully exited causing the subsequent run to fail.
There is a breaking change in this PR, previously if kill was called on an
InterruptHandlebefore or while a guest call was not in progress the next guest call made on theSandboxwould be cancelled , now this scenario is a no-op. kill only takes effect if there is a guest call running.
