-/* We would like to have fast thread local variables that behave in
-   the same way as C and C++ thread local variables.  This would mean
-   having an field attribute "thread" (like static, final, etc.).
-   However, this is not compatible with java semantics, which we wish
-   to support transparently.  The problems we must overcome are:
-
-   * In Java, ThreadLocal variables are not statically allocated: they
-     are objects, created at runtime.
-
-   * Class ThreadLocal is not final and neither are its methods, so it
-     is possible to create a subclass of ThreadLocal that overrides
-     any method.
-
-   * __thread variables in DSOs are not visible to the garbage
-     collector, so we must ensure that we keep a copy of every thread
-     local variable somewhere on the heap.
-
-   * Once a ThreadLocal instance has been created and assigned to a
-     static field, that field may be reassigned to a different
-     ThreadLocal instance or null.  
-
-   So, we can't simply replace get() and set() with accesses of a
-   __thread variable.
-
-   So, we create a pthread_key in each ThreadLocal object and use that
-   as a kind of "look-aside cache".  When a ThreadLocal is set, we
-   also set the corresponding thread-specific value.  When the
-   ThreadLocal is collected, we delete the key.
-
-   This scheme is biased towards efficiency when get() is called much
-   more frequently than set().  It is slightly internaler than the
-   all-Java solution using the underlying map in the set() case.
-   However, get() is very much more frequently invoked than set().
