Crash if db.close() is called in process.on('exit')

[mhdawson]

This code was in a sample application that was looking at

 process.on('exit', (code) => {
 db.close((err) => {
 logger.error('Error closing DB: ' + err.message);
 });

And it resulted in a consistent crash with the stack trace as shown in the comment on this issue: nodejs/node-addon-api#902 (comment)

My question is whether closeing the db in the exit handler is expected to work or if this is a case of user error
