If NODE_REPL_HISTORY file cannot be opened, Node crashes

[bminer]

If the NODE_REPL_HISTORY file cannot be opened (i.e. read-only file system, permission issue, etc.), Node simply crashes. This is probably an uncaught "error" event.

This behavior seems silly to me. The NODE_REPL_HISTORY file is a convenience, not a requirement. Even though it can be disabled by an environment flag, if it cannot be opened, it should silently fail. Or, perhaps, NODE_REPL_HISTORY should be disabled by default?

Thoughts?

I guess it can just log you an error. I think this was brought up before?
