Roland,
My question is about the precise lifetime of a td_thrhandle_t, in both
LinuxThreads' and NPTL's thread_db implementations. Right now, GDB
re-queries for the thread handles every time the target stops. This hurts a
lot... from the implementation, I believe they'll remain valid over time,
until the thread exits. Is this right/reasonable?
I'm not worried if one thread handle could be eventually re-used for another
thread after the first exits; we'll notice the thread exit, discard the
thread handle, and go on with our lives.

I don't know what a "thread handle" is. Please refer to the API types directly.

Which is to say, if you are really talking about `td_thrhandle_t', then
that is a momentary object that exists only on gdb's stack during some
thread_db calls. The th_unique value inside it does indeed have a reliable
valid lifetime matching that of the inferior thread.
