US FOI: Is there a "Secret Hold" on the Freedom of Information bill?

I've reported a few times here about the progress of the Open Govt Bill through the US Congrees, this article on open the government.org points to a delaying tactic holding it up, things may obviously change now

"The Senate Judiciary Committee approved a bill on Sept. 21 that would greatly strengthen government openness - but one sponsor suspects it is being blocked by a parliamentary device called a "secret hold."

One aim of the Bill is create a form of Ombudsman's Office for the US FOIA called the Office of Government Services. See my previous post on the Bill
