fwiw, I did this in a libgdbserver patch that we use here.
gdbserver needs to call back to gdb to do symbol resolution, which is
needed as part of libthread_db init, but the program that links in
libgdbserver may want to attach to all threads before gdb has
connected, so I opendir /proc/<pid>/task and read in the lwps.
