Your threads should know which ThreadLocal they have used, so you
should be able to get away with ThreadLocal.remove().

I would perhaps subclass Thread to PoolableThread and therein define
a method reset() or something, which will call that method for all
known used ThreadLocal, and clear other semi persistent state. This
method would be called when returning the PoolableThread to the pool.
