* Transitions a sandbox to the SANDBOX_ERROR state.

|
* This can occur during initialization or execution
|
|
* Unmaps linear memory, removes from the runqueue (if on it), and adds to the completion queue
|
|
* Because the stack is still in use, freeing the stack is deferred until later
|
|
*
|
|
* TODO: Is the sandbox adding itself to the completion queue here? Is this a problem? Issue #94

|
* @param sandbox the sandbox erroring out
|
|
* @param last_state the state the sandbox is transitioning from. This is expressed as a constant to
|
|
* enable the compiler to perform constant propagation optimizations.
