Don't special-case GeneratorExit in Condition.wait().
Don't special-case GeneratorExit in Condition.wait().

I can't remember why I added that code, there are no tests for it, and
it causes a spurious "Exception ignored in <generator object ...>"
error message if code like this is interrupted during the wait():

@coroutine
def gen():
    with (yield from cond):
        while <test>:
            yield from cond.wait()
