Improve error handling in streaming/index.js (#5968) 

On an unhandled worker exception, we should log the exception
and exit with nonzero status, instead of letting workers
silently fail and restarting them in an endless loop.

Note: we previously tried to handle the `'error'` signal.
That's not a signal Node fires; my patch traps `'uncaughtException'`,
which is what the code was _trying_ to do.
