a small improvement on the way clear_completed and clear_failed are

[guilherme]

When the status queue is too big, wait to clear_completed and clear_failed to check all items if they are completed/failed and them remove the items takes too much time. This approach removes when encounters the completed?/failed? item and then keeps returning the hashs of removed items.

And i've removed the glueoutputbuf from redis-test.conf since it doesn't work on redis >= 2.6

Thanks - this saves an extra iteration through the list of items too :+1:
