At the time of the original error, are all your threads in the thread
list?  GDB's internal thread_list variable, not the result of "info
threads", which will check for new threads.

If they are, and they do not have private info set, what added them to
the thread list?  I missed one function; maybe they were added by
add_thread_silent?
