Recently one of my colleagues introduced me to a class from the JDK with which I was not familiar: ThreadLocal. This class allows you to put local data on a thread, so that every module running in the thread can access it. ThreadLocal has been around since JDK 1.2, but hasn't been used much, maybe because of a first, rather poor implementation, performance-wise.
