This commit adds information regarding catching uncaughtExceptions to the process doc. As brought up in #5147 the documentation does not state the recursion guard implemented in 2b252ac.

This might be worded better to simply say that if an exception is thrown from within an uncaughtException event handler, the process will die, and it is handled that way to avoid infinite recursion.

Also I'm not sure if it's really useful to suggest using something like process.nextTick() to avoid this since that could easily cause the same problem of creating an infinite loop of sorts.

LGTM. Should we give an example?

LGTM, I'm -0 on an example. I wonder if die is good terminology here.

I'd replace it with exit with a non-zero status code.

Yes, exit/terminate with a non-zero status code sounds much better.

Alright, the latest commit changes the wording from die to exiting with a non zero exit code.
