--------------------------------------

This is not an uncommon problem, I just ran into it, only noticing the leak because I was running an experiment.  Thanks.

> The EC2 driver automatically creates tags for new nodes in create_node(). Rarely, this can fail with an InvalidInstanceID.NotFound error from EC2. This error bubbles up to the create_node caller and prevents the new node information from being returned.
> I've seen similar issues before on EC2 when doing a instance query right after a launch. The new node isn't always included in the result, perhaps due to some caching or data propagation issue. I suspect the same thing is happening in the tag creation API. Perhaps the ex_create_tags calls could be wrapped in a try/except with this error logged and ignored.

> I also captured the libcloud request/response log and can provide that if needed.
