+    gthread-jni.c
+
+    Also implements a registry for threads, mapping Thread objects to small

+    joinable, so that they will be garbage collected.
+
+    There are a number of possible alternative implementations.
+    
+    
+    The rest of this comment consists of an answer to a question that was
+    raised on the commit-classpath mailing list:
+
+    Mark Wielaard wrote:

+
+
+    I agree with you on the pointer size issues.  A gpointer is a void *, so
+    it's certainly guaranteed to be at least as large as any other
+    pointer. And a jobject is implicitly an opaque pointer (in Jikes RVM, we
+    use small integers, but we coerce them into the representation of a
+    pointer).
+
+    The int <==> Thread mapping addresses a different issue.  I realize that I
+    did not document this properly (two and a half lines in thread_create),
+    and the point is subtle (at least to me; took me a while to figure out).
+
+    The int => Thread mapping always returns jobjects that are local
+    references, not global ones.  This is because Thread objects need to be
+    able to go away and be garbage collected after the thread they refer to
+    has died.
+
+    If we keep a global object reference to a thread, then when do we delete
+    that global object reference?  We have an answer in the case of GThread
+    objects that were explicitly created with the joinable attribute.  It is
+    safe for us to maintain a global reference to any joinable thread, since
+    the joinable thread must linger (even if only in a zombie state)
+    until it's explicitly joined via a g_thread_join() call.  The global ref
+    could be cleaned up at that point too.
+
+    However, in the case of GThreads that were created non-joinable by
+    g_thread_create(), and in the case of Java threads that were created
+    within pure Java code (not via g_thread_create()), we don't want them to
+    linger forever, and there is no way to tell when the last reference
+    to such threads needs to expire.  In the case of this application -- AWT
+    with GTK peers -- it would probably be safe anyway, since there are not
+    very many threads we create, but I was going for correctness even in the
+    case of long-running programs that might set up and tear down AWT
+    interfaces many times.
+
+    So, I duplicated the POSIX thread-ID semantics.  The thread ID of a
+    non-joinable thread remains valid as long as that thread is still alive.
+    Once that thread dies, the old thread ID may be reused at any moment.  And
+    that's why the array indexed by thread ID numbers is an array of weak
+    references.
+
+    That's also why the int => Thread jobject mapping function always returns
+    local references, since global references would lock the Thread in memory
+    forever.
+
+    I would dearly love there to be a cleaner solution.  I dislike the
+    repeated dips from C code into Java that are necessary to look up thread
+    ID numbers.  If anyone can think of one, I'm all ears.
