When we migrate the Connector API to Java 1.5, we must rewrite all references to util.concurrent to the new package java.util.concurrent defined in the JSR-166[ http://www.jcp.org/en/jsr/detail?id=166 ]. When we do that, if we still want to support older Java versions (we will), we must include the backport from JSR-166 provided by Dawid Kurzyniec [ http://www.mathcs.emory.edu/dcl/util/backport-util-concurrent/ ].

I didn't set a version for this because it might be a painful step, and I believe that after the Winter is a better time to tackle this.
