You can easily override the default signal handlers.
See http://nodejs.org/docs/latest/api/process.html#process_signal_events
you could do:
```
function gracefulExit() {
db.close(process.exit)
}
process.on('SIGINT' gracefulExit).on('SIGTERM', gracefulExit)
```
Obviously it can be more sophisticated, with timeouts, etc.
