Do all of the connections have to be closed before the metadata will be
updated? I was looking at this last night and it seems that over time
the IdleRemover should eventually close all of the connections. Is this
correct? If so, then at some point in the future all of the metadata
would be refreshed and a restart would not be necessary? What do you think?
