That's not an accurate comparison. The issue is not the stack unwinding, but the root cause of the panic. In all of those other languages, exceptions are used for normal error handling in addition to "fatal" events. In Go, panics, if used at all, are generally used for fatal runtime errors (memory, segfault, etc), or in place of assert, and indicates a fatal, unrecoverable flaw in your program.

At every job I've worked at it was generally discouraged to handle MemoryError exceptions in python and OutOfMemoryError exceptions in Java. It's safer to assume there is nothing you can do on such occasions, because sometimes (usually the worst possible time) there isn't.

Another relevant Java example might be VirtualMachineError (superclass of OutOfMemoryError) and the wonderfully named subclass UnknownError(!).
