I asked a question yesterday that is no longer relevant and have voted to close it as such. I was thinking that flagging it for moderator attention would be a good idea to expedite the process, but do not have the ability to flag my own question as such.
I only have the option to edit, close, and delete...
Another potential option is on the vote to close option. If the OP votes to close the question, maybe it should not require the 5 votes to do so?
