This PR makes two changes:
If
WebAssembly.RuntimeError
is raised and bubbles all the way up to the top level, catch it and report the problem as unrecoverable onconsole.error()
. Then close the communication channel, terminating the worker thread.If a communication channel has been closed, reject any promises trying to write on the channel with a

WebAssembly.RuntimeError
.
