for bug #257381 ("[Discovery] Reduce BREE to Java 1.4")  ECF needs a
backport of java.util.concurrent. The Distributed Computing Laboratory
at Emory University  provides such a backport and in my local tests
the lib seems to keep its promises.
Is anybody interested in such a backport in Orbit? Does it make sense to
have it in Orbit? If not, I won't go through the hassle of creating an
Orbit-esque version and simple embed it in the ECF consumer bundle.
