Eric Harney 7f3a77b66f Prevent double-attachment race in attachment_reserve ... If multiple attachments are requested simultaneously, a volume can be attached to an instance more than once. This fixes this problem by detecting that a race has occurred in _attachment_reserve, and backing out one of the invalid attachment records. This means that if the attachment API is called repeatedly and quickly for the same volume, some requests may fail, but this is much better than incorrectly creating multiple attachments.
