Oh, and one other thing that I like to mention when this comes up.  My
previous message was the implementation issues involved; this one's the
motivational issue.  Thread_db is not, and can't/shouldn't be,
available in a cross environment.  We have done a lot of work to make
GDB read corefiles in a cross environment; and at MontaVista we've seen
a large demand for this functionality from our customers.  So using
thread_db with corefiles doesn't meet our (GDB developers') goals, I
think.
