After adding a batch of new server tests, some interactions between
tests have shown up via a shared database. This sets an existing flag
for dealing with this problem, that is used during browser tests but
hadn't been needed before for server tests.
Summary:
- Node has a strong recommendation to assume bad state and exit promptly on
unhandled exceptions and rejections. We follow it, and only make an effort to
clean up before exiting, and to log the error in a more standard way.
- The only case seen in recent month of an unhandled rejection was for
attempting to write overly large JSON to a Client websocket. Ensure that's
handled, and add a test case that artificially reproduces this scenario.
Test Plan:
Added a test case for failing write to Client, and a test case that unhandled
errors indeed kill the server but with an attempt at cleanup.
