Cool, thanks.  I've reviewed and applied all your changes (with
some relatively minor edits).  In particular, I don't think the
workaround you added in linuxthreads_db/td_symbol_list.c for
LINUXTHREADS_PTHREAD_THREADS_MAX is really necessary once the
__linuxthreads_pthread_threads_max has been added to manager.c.
Can you check if everything works properly with the latest and
greatest?

diff -u is just perfect...
