The ThreadLocal class uses a collection that has a large
granularity synchronization lock. This lock could be narrowed
so that calls to get a ThreadLocal value are effecient.

On a cursory glance ThreadLocal is used in String in the JDK
for chartobyte encodings and has suggested uses for app
developers. Here is the authors comments

This class duplicates the functionality of
java.lang.ThreadLocal with substantially improved performance.
The speed of ThreadLocal.get is improved by a factor of 5 when using
the classic VM and 2.5 when using HotSpot. The implementation of <i>get</i>
only requires synchronization when a new entry is being created.
