From the iojs docs: > An unhandled exception means your application - and by extension io.js itself - > is in an undefined state. Blindly resuming means anything could happen. > > Think of resuming as pulling the power cord when you are upgrading your system. > Nine out of ten times nothing happens - but the 10th time, your system is bust. > > uncaughtException should be used to perform synchronous cleanup before shutting > down the process. It is not safe to resume normal operation after > uncaughtException. If you do use it, restart your application after every > unhandled exception!
