Help with error handling

[rafalkrupinski]

Haven's seen any docs, examples or tests related to error handling.

There's .errors operator that should return the error stream.

I tried to use it like this (test case):

def test_error():
    evt = Event()

    def err():
        raise ValueError()

    errors = evt.map(err, ordered=False).errors()

    evt()

    errors.run()

but it just waits indefinitely.
